# Preview a transform

Authentication: required

## Paths

- `POST` (also `GET`) `/_transform/{transform_id}/_preview`
- `POST` (also `GET`) `/_transform/_preview`

#### Path parameters

- `transform_id` (string) — optional, leave it out to use `/_transform/_preview`
  Identifier for the transform to preview. If you specify this path parameter, you cannot provide transform
configuration details in the request body.

## Description

Generates a preview of the results that you will get when you create a transform with the same configuration.

It returns a maximum of 100 results. The calculations are based on all the current data in the source index. It also
generates a list of mappings and settings for the destination index. These values are determined based on the field
types of the source index and the transform aggregations.

## Required privileges

- Index privileges: `read`, `view_index_metadata`
- Cluster privileges: `manage_transform`

## Query string parameters

- `timeout` (union oneOf · default: 30s) — optional
  Period to wait for a response. If no response is received before the
timeout expires, the request fails and returns an error.
  Values: `-1`, `0`

## Request body

`application/json`

- `dest` (object) — optional
  The destination for the transform.
  - `index` (string) — optional
    The destination index for the transform. The mappings of the destination index are deduced based on the source
fields when possible. If alternate mappings are required, use the create index API prior to starting the
transform.
  - `aliases` (object[]) — optional
    The aliases that the destination index for the transform should have.
Aliases are manipulated using the stored credentials of the transform, which means the secondary credentials
supplied at creation time (if both primary and secondary credentials are specified).

The destination index is added to the aliases regardless of whether the destination index was created by the
transform or pre-created by the user.
    - `alias` (string) — required
      The name of the alias.
    - `move_on_creation` (boolean · default: false) — optional
      Whether the destination index should be the only index in this alias.
If `true`, all the other indices will be removed from this alias before adding the destination index to this
alias. This does not delete the removed indices; it only removes them from the alias.
  - `pipeline` (string) — optional
    The unique identifier for an ingest pipeline.
- `description` (string) — optional
  Free text description of the transform.
- `frequency` (union oneOf · default: 1m) — optional
  The interval between checks for changes in the source indices when the
transform is running continuously. Also determines the retry interval in
the event of transient failures while the transform is searching or
indexing. The minimum value is 1s and the maximum is 1h.
  Values: `-1`, `0`
- `pivot` (object) — optional
  The pivot method transforms the data by aggregating and grouping it.

        The number of buckets returned out of the overall terms list.
      - `format` (string) — optional
- `source` (object) — optional
  The source of the data for the transform.
  - `index` (union oneOf) — required
    The source indices for the transform. It can be a single index, an index pattern (for example, `"my-index-*""`), an
array of indices (for example, `["my-index-000001", "my-index-000002"]`), or an array of index patterns (for
example, `["my-index-*", "my-other-index-*"]`. For remote indices use the syntax `"remote_name:index_name"`. If
any indices are in remote clusters then the master node and at least one transform node must have the `remote_cluster_client` node role.
    One of: `string[]` or `string`
  - `query` ({} Query) — optional
    A query clause that retrieves a subset of data from the source index.
    See [Query](https://www.elastic.co/docs/api/doc/elasticsearch-serverless/types/_types-query_dsl-querycontainer)
  - `runtime_mappings` (object) — optional
    Definitions of search-time runtime fields that can be used by the transform. For search runtime fields all data
nodes, including remote nodes, must be 7.12 or later.
- `settings` (object) — optional
  Defines optional transform settings.
  - `align_checkpoints` (boolean · default: true) — optional
    Specifies whether the transform checkpoint ranges should be optimized for performance. Such optimization can align
checkpoint ranges with the date histogram interval when date histogram is specified as a group source in the
transform config. As a result, less document updates in the destination index will be performed thus improving
overall performance.
  - `dates_as_epoch_millis` (boolean · default: false) — optional
    Defines if dates in the output should be written as ISO formatted string or as millis since epoch. epoch_millis was
the default for transforms created before version 7.11. For compatible output set this value to `true`.
  - `deduce_mappings` (boolean · default: true) — optional
    Specifies whether the transform should deduce the destination index mappings from the transform configuration.
  - `docs_per_second` (number) — optional
    Specifies a limit on the number of input documents per second. This setting throttles the transform by adding a
wait time between search requests. The default value is null, which disables throttling.
  - `max_page_search_size` (number) — optional
    Defines the initial page size to use for the composite aggregation for each checkpoint. If circuit breaker
exceptions occur, the page size is dynamically adjusted to a lower value. The minimum value is `10` and the
maximum is `65,536`. The default value is `500` for `pivot` transforms and `5000` for `latest` transforms.
  - `use_point_in_time` (boolean · default: true) — optional
    Specifies whether the transform checkpoint will use the Point In Time API while searching over the source index.
In general, Point In Time is an optimization that will reduce pressure on the source index by reducing the amount
of refreshes and merges, but it can be expensive if a large number of Point In Times are opened and closed for a
given index. The benefits and impact depend on the data being searched, the ingest rate into the source index, and
the amount of other consumers searching the same source index.
  - `num_failure_retries` (number) — optional
    Defines the number of retries on a recoverable failure before the transform task is marked as `failed`.
The minimum value is `0` and the maximum is `100`, where `-1` indicates that the transform retries indefinitely.
If unset, the cluster-level setting `num_transform_failure_retries` is used.

This setting cannot be specified when `unattended` is `true`, because unattended transforms always retry
indefinitely.
  - `unattended` (boolean · default: false) — optional
    If `true`, the transform runs in unattended mode. In unattended mode, the transform retries indefinitely in case
of an error which means the transform never fails. Setting the number of retries other than infinite fails in
validation.
  - `indexer_request_timeout` (union string) — optional — nullable
    The initial timeout for the requests the transform sends to nodes to retrieve checkpoint information.
Each consecutive failure doubles the timeout, up to a maximum of `12h`. The minimum value is `1ms` and the
maximum is `12h`. Defaults to `30s`.
    Values: `-1`, `0`
- `sync` (object) — optional
  Defines the properties transforms require to run continuously.
  - `time` (object) — optional
    Specifies that the transform uses a time field to synchronize the source and destination indices.
    - `delay` (union oneOf · default: 60s) — optional
      The time delay between the current time and the latest input data time.
      Values: `-1`, `0`
    - `field` (string) — required
      The date field that is used to identify new documents in the source. In general, it’s a good idea to use a field
that contains the ingest timestamp. If you use a different field, you might need to set the delay such that it
accounts for data transmission delays.
- `retention_policy` (object) — optional
  Defines a retention policy for the transform. Data that meets the defined
criteria is deleted from the destination index.
  - `time` (object) — optional
    Specifies that the transform uses a time field to set the retention policy.
    - `field` (string) — required
      The date field that is used to calculate the age of the document.
    - `max_age` (union oneOf) — required
      Specifies the maximum age of a document in the destination index. Documents that are older than the configured
value are removed from the destination index.
      Values: `-1`, `0`
- `latest` (object) — optional
  The latest method transforms the data by finding the latest document for
each unique key.
  - `sort` (string) — required
    Specifies the date field that is used to identify the latest documents.
  - `unique_key` (string[]) — required
    Specifies an array of one or more fields that are used to group the data.

effectively stores data the same way as a text field that only indexes documents (index_options: docs) and
disables norms (norms: false). Term queries perform as fast if not faster as on text fields, however queries
that need positions such as the match_phrase query perform slower as they need to look at the _source document
to verify whether a phrase matches. All queries return constant scores that are equal to 1.0.

        - `element_type` (enum · default: float)
          The data type used to encode vectors. The supported data types are `float` (default), `byte`, and `bit`.

Supported values include:
  - `bit`: Indexes a single bit per dimension. Useful for very high-dimensional vectors or models that specifically support
bit vectors.

NOTE: when using `bit`, the number of dimensions must be a multiple of `8` and must represent the number of bits.
  - `byte`: Indexes a 1-byte integer value per dimension.
  - `float`: Indexes a 4-byte floating-point value per dimension.
          Values: `bit`, `byte`, `float`
        - `index` (boolean · default: true)
          If `true`, you can search this field using the kNN search API.
        - `index_options` (object)
          An optional section that configures the kNN indexing algorithm. The HNSW algorithm has two internal parameters
that influence how the data structure is built. These can be adjusted to improve the accuracy of results, at the
expense of slower indexing speed.

This parameter can only be specified when `index` is `true`.
          - `confidence_interval` (number) — deprecated
            The confidence interval to use when quantizing the vectors. Can be any value between and including `0.90` and
`1.0` or exactly `0`. When the value is `0`, this indicates that dynamic quantiles should be calculated for
optimized quantization. When between `0.90` and `1.0`, this value restricts the values used when calculating
the quantization thresholds.

For example, a value of `0.95` will only use the middle `95%` of the values when calculating the quantization
thresholds (e.g. the highest and lowest `2.5%` of values will be ignored).

Defaults to `1/(dims + 1)` for `int8` quantized vectors and `0` for `int4` for dynamic quantile calculation.

Only applicable to `int8_hnsw`, `int4_hnsw`, `int8_flat`, and `int4_flat` index types.
          - `ef_construction` (number · default: 100)
            The number of candidates to track while assembling the list of nearest neighbors for each new node.

Only applicable to `hnsw`, `int8_hnsw`, `bbq_hnsw`, and `int4_hnsw` index types.
          - `m` (number · default: 16)
            The number of neighbors each node will be connected to in the HNSW graph.

Only applicable to `hnsw`, `int8_hnsw`, `bbq_hnsw`, and `int4_hnsw` index types.
          - `type` (enum)
            The type of kNN algorithm to use.

Supported values include:
  - `bbq_flat`: This utilizes a brute-force search algorithm in addition to automatically quantizing to binary vectors.
Only supports `element_type` of `float`.
  - `bbq_hnsw`: This utilizes the HNSW algorithm in addition to automatic binary quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by nearly 32x at the cost of some accuracy.
  - `flat`: This utilizes a brute-force search algorithm for exact kNN search. This supports all `element_type` values.
  - `hnsw`: This utilizes the HNSW algorithm for scalable approximate kNN search. This supports all `element_type` values.
  - `int4_flat`: This utilizes a brute-force search algorithm in addition to automatically half-byte scalar quantization.
Only supports `element_type` of `float`.
  - `int4_hnsw`: This utilizes the HNSW algorithm in addition to automatically scalar quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by 8x at the cost of some accuracy.
  - `int8_flat`: This utilizes a brute-force search algorithm in addition to automatically scalar quantization. Only supports
`element_type` of `float`.
  - `int8_hnsw`: The default index type for `float` vectors. This utilizes the HNSW algorithm in addition to automatically scalar
quantization for scalable approximate kNN search with `element_type` of `float`.

This can reduce the memory footprint by 4x at the cost of some accuracy.
            Values: `bbq_flat`, `bbq_hnsw`, `flat`, `hnsw`, `int4_flat`, `int4_hnsw`, `int8_flat`, `int8_hnsw`
          - `rescore_vector` (object)
            The rescore vector options. This is only applicable to `bbq_disk`, `bbq_hnsw`, `int4_hnsw`, `int8_hnsw`, `bbq_flat`, `int4_flat`, and `int8_flat` index types.
            - `oversample` (number)
              The oversampling factor to use when searching for the nearest neighbor. This is only applicable to the quantized formats: `bbq_*`, `int4_*`, and `int8_*`.
When provided, `oversample * k` vectors will be gathered and then their scores will be re-computed with the original vectors.

valid values are between `1.0` and `10.0` (inclusive), or `0` exactly to disable oversampling.
        - `similarity` (enum)
          The vector similarity metric to use in kNN search.

Documents are ranked by their vector field's similarity to the query vector. The `_score` of each document will
be derived from the similarity, in a way that ensures scores are positive and that a larger score corresponds
to a higher ranking.

Defaults to `l2_norm` when `element_type` is `bit` otherwise defaults to `cosine`.

`bit` vectors only support `l2_norm` as their similarity metric.

This parameter can only be specified when `index` is `true`.

Supported values include:
  - `cosine`: Computes the cosine similarity. During indexing Elasticsearch automatically normalizes vectors with `cosine`
similarity to unit length. This allows to internally use `dot_product` for computing similarity, which is more
efficient. Original un-normalized vectors can be still accessed through scripts.

The document `_score` is computed as `(1 + cosine(query, vector)) / 2`.

The `cosine` similarity does not allow vectors with zero magnitude, since cosine is not defined in this case.
  - `dot_product`: Computes the dot product of two unit vectors. This option provides an optimized way to perform cosine similarity.
The constraints and computed score are defined by `element_type`.

When `element_type` is `float`, all vectors must be unit length, including both document and query vectors.

The document `_score` is computed as `(1 + dot_product(query, vector)) / 2`.

When `element_type` is `byte`, all vectors must have the same length including both document and query vectors or
results will be inaccurate.

The document `_score` is computed as `0.5 + (dot_product(query, vector) / (32768 * dims))` where `dims` is the
number of dimensions per vector.
  - `l2_norm`: Computes similarity based on the `L2` distance (also known as Euclidean distance) between the vectors.

The document `_score` is computed as `1 / (1 + l2_norm(query, vector)^2)`.

For `bit` vectors, instead of using `l2_norm`, the `hamming` distance between the vectors is used.

The `_score` transformation is `(numBits - hamming(a, b)) / numBits`.
  - `max_inner_product`: Computes the maximum inner product of two vectors. This is similar to `dot_product`, but doesn't require vectors
to be normalized. This means that each vector’s magnitude can significantly effect the score.

The document `_score` is adjusted to prevent negative values. For `max_inner_product` values `< 0`, the `_score`
is `1 / (1 + -1 * max_inner_product(query, vector))`. For non-negative `max_inner_product` results the `_score`
is calculated `max_inner_product(query, vector) + 1`.
          Values: `cosine`, `dot_product`, `l2_norm`, `max_inner_product`

You can explicitly set it to skip rollover.
      - `origination_date` (number · default: 0)
        If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting
if you create a new index that contains old data and want to use the original creation date to calculate the index
age. Specified as a Unix epoch value in milliseconds.
      - `parse_origination_date` (boolean)
        Set to true to parse the origination date from the index name. This origination date is used to calculate the index age
for its phase transitions. The index name must match the pattern ^.*-{date_format}-\\d+, where the date_format is
yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format,
for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.
      - `step` (object)
        - `wait_time_threshold` (union oneOf)

      - `rollover_alias` (string)
        The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action.
When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more
information about rolling indices, see Rollover.
      - `prefer_ilm` (boolean | string · default: true)
        Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are

    - `translog` (object)
      - `sync_interval` (union oneOf · default: 5s)

Values less than 100ms are not allowed.
        Values: `-1`, `0`
      - `durability` (enum · default: string)
        Whether or not to `fsync` and commit the translog after every index, delete, update, or bulk request.

Supported values include:
  - `request` (or `REQUEST`): (default) fsync and commit after every request. In the event of hardware failure, all acknowledged writes
will already have been committed to disk.
  - `async` (or `ASYNC`): fsync and commit in the background every sync_interval. In the event of a failure, all acknowledged writes
since the last automatic commit will be discarded.
        Values: `request`, `REQUEST`, `async`, `ASYNC`
      - `flush_threshold_size` (number | string · default: 512mb)
        The translog stores all operations that are not yet safely persisted in Lucene (i.e., are not
part of a Lucene commit point). Although these operations are available for reads, they will need
to be replayed if the shard was stopped and had to be recovered. This setting controls the
maximum total size of these operations, to prevent recoveries from taking too long. Once the
maximum size has been reached a flush will happen, generating a new Lucene commit point.
      - `retention` (object)
        - `size` (number | string · default: 512mb)
          This controls the total size of translog files to keep for each shard. Keeping more translog files increases
the chance of performing an operation based sync when recovering a replica. If the translog files are not
sufficient, replica recovery will fall back to a file based sync. This setting is ignored, and should not be
set, if soft deletes are enabled. Soft deletes are enabled by default in indices created in Elasticsearch
versions 7.0.0 and later.
        - `age` (union oneOf · default: 12h)
          This controls the maximum duration for which translog files are kept by each shard. Keeping more
translog files increases the chance of performing an operation based sync when recovering replicas. If
the translog files are not sufficient, replica recovery will fall back to a file based sync. This setting
is ignored, and should not be set, if soft deletes are enabled. Soft deletes are enabled by default in
indices created in Elasticsearch versions 7.0.0 and later.

      - **type: scripted** (`type: scripted`)
        - `type` (enum)
          Values: `scripted`
        - `script` (string)
        - `weight_script` (string)
    - `mapping` (object)
      Enable or disable dynamic mapping for an index.
      - `coerce` (boolean)
      - `total_fields` (object)
        - `limit` (number | string · default: 1000)
          The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit.
The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance
degradations and memory issues, especially in clusters with a high load or few resources.
        - `ignore_dynamic_beyond_limit` (boolean | string · default: false)
          This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set
to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail
with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail.
Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false.
The fields that were not added to the mapping will be added to the _ignored field.
      - `depth` (object)
        - `limit` (number · default: 20)
          The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined
at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.
      - `nested_fields` (object)
        - `limit` (number · default: 50)
          The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when
arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this
setting limits the number of unique nested types per index.
      - `nested_objects` (object)
        - `limit` (number · default: 10000)
          The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps
to prevent out of memory errors when a document contains too many nested objects.
      - `field_name_length` (object)
        - `limit` (number)
          Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but
might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The
default is okay unless a user starts to add a huge number of fields with really long names. Default is `Long.MAX_VALUE` (no limit).
      - `dimension_fields` (object)
        - `limit` (number)
          [preview] This functionality is in technical preview and may be changed or removed in a future release.
Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
      - `source` (object)
        - `mode` (enum)
          Values: `disabled`, `stored`, `synthetic`
      - `ignore_malformed` (boolean | string)
    - `indexing.slowlog` (object)
      - `level` (string)
      - `source` (number)
      - `reformat` (boolean)
      - `threshold` (object)
        - `index` (object)
          The indexing slow log, similar in functionality to the search slow log. The log file name ends with `_index_indexing_slowlog.json`.
Log and the thresholds are configured in the same way as the search slowlog.
          - `warn` (union oneOf)
            Values: `-1`, `0`
          - `info` (union oneOf)
            Values: `-1`, `0`
          - `debug` (union oneOf)
            Values: `-1`, `0`
          - `trace` (union oneOf)
            Values: `-1`, `0`
    - `indexing_pressure` (object)
      Configure indexing back pressure limits.
      - `memory` (object)
        - `limit` (number)
          Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded,
the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit,
the node will reject new replica operations. Defaults to 10% of the heap.
    - `store` (object)
      The store module allows you to control how index data is stored and accessed on disk.
      - `type` (union anyOf)
        

Supported values include:
  - `fs`: Default file system implementation. This will pick the best implementation depending on the operating environment, which
is currently hybridfs on all supported systems but is subject to change.
  - `niofs`: The NIO FS type stores the shard index on the file system (maps to Lucene NIOFSDirectory) using NIO. It allows multiple
threads to read from the same file concurrently. It is not recommended on Windows because of a bug in the SUN Java
implementation and disables some optimizations for heap memory usage.
  - `mmapfs`: The MMap FS type stores the shard index on the file system (maps to Lucene MMapDirectory) by mapping a file into
memory (mmap). Memory mapping uses up a portion of the virtual memory address space in your process equal to the size
of the file being mapped. Before using this class, be sure you have allowed plenty of virtual address space.
  - `hybridfs`: The hybridfs type is a hybrid of niofs and mmapfs, which chooses the best file system type for each type of file
based on the read access pattern. Currently only the Lucene term dictionary, norms and doc values files are memory
mapped. All other files are opened using Lucene NIOFSDirectory. Similarly to mmapfs be sure you have allowed
plenty of virtual address space.
        Values: `fs`, `niofs`, `mmapfs`, `hybridfs`
      - `allow_mmap` (boolean)
        You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap.
This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This
setting is useful, for example, if you are in an environment where you can not control the ability to create a lot
of memory maps so you need disable the ability to use memory-mapping.
      - `stats_refresh_interval` (union oneOf)
        How often store statistics are refreshed
        Values: `-1`, `0`
  - `defaults` (object)
    Default settings, included when the request's `include_default` is `true`.
    Same fields as `settings` in `generated_dest_index`
  - `data_stream` (string)
  - `lifecycle` (object)
    Data stream lifecycle applicable if this is a data stream.
    - `data_retention` (union oneOf)
      If defined, every document added to this data stream will be stored at least for this time frame.
Any time after this duration the document could be deleted.
When empty, every document in this data stream will be stored indefinitely.
      Values: `-1`, `0`
    - `effective_retention` (union oneOf)
      The least amount of time data should be kept by elasticsearch.
      Values: `-1`, `0`
    - `retention_determined_by` (enum)
      Configuration source that can influence the retention of a data stream.
      Values: `data_stream_configuration`, `default_global_retention`, `max_global_retention`, `default_failures_retention`
    - `downsampling` (object[])
      The list of downsampling rounds to execute as part of this downsampling configuration
      - `after` (union oneOf)
        The duration since rollover when this downsampling round should execute
        Values: `-1`, `0`
      - `fixed_interval` (string)
        The downsample interval.
    - `downsampling_method` (enum)
      The method used to downsample the data. There are two options `aggregate` and `last_value`. It requires
`downsampling` to be defined. Defaults to `aggregate`.
      Values: `aggregate`, `last_value`
    - `enabled` (boolean · default: true)
      If defined, it turns data stream lifecycle on/off (`true`/`false`) for this data stream. A data stream lifecycle
that's disabled (enabled: `false`) will have no effect on the data stream.
- `preview` (object[])
