## Description

This codec renders each processed event as a dot (`.`). It is typically used with the `java_stdout` output to provide approximate event throughput. It is especially useful when combined with `pv` and `wc -c` as follows:
```bash
  bin/logstash -f /path/to/config/with/jdots/codec | pv | wc -c
```
