# Data node added
A new data node joined the cluster. Until shard rebalancing finishes, existing nodes might carry more shards and later load than usual.

## Insight details


| Field     | Value                                  |
|-----------|----------------------------------------|
| Component | Elasticsearch                          |
| Severity  | Low                                    |
| Scope     | Cluster                                |
| Domains   | performance, node-lifecycle, stability |


## Example: What you might see in AutoOps

The following is an example of what you might see when this insight is triggered. Real insights use live data and links from your deployment or cluster.

### Data node was added to cluster


#### What was detected

A data node joined the cluster: es-data-01.

#### Recommendations

No recommendations are linked to this insight.

#### Background and impact

Data nodes store shards and handle indexing and search for assigned data. When a new data node joins, the cluster might relocate shards to use the added capacity.
During rebalancing, existing nodes can carry more shards and later disk or CPU load until allocation settles.
