# Replication settings
|
|||
|
|
|
|||
|
|
The replication plugin adds several settings to the standard OpenSearch cluster settings.
|
|||
|
|
The settings are dynamic, so you can change the default behavior of the plugin without restarting your cluster.
|
|||
|
|
You can mark settings as `persistent` or `transient`.
|
|||
|
|
|
|||
|
|
For example, to update the retention period of the result index:
|
|||
|
|
|
|||
|
|
```json
|
|||
|
|
PUT _cluster/settings
|
|||
|
|
{
|
|||
|
|
"persistent": {
|
|||
|
|
"plugins.replication.indices.recovery.parallel_chunks": "8"
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
These settings manage the resources consumed by remote recoveries. We don’t recommend changing these settings; the defaults should work well for most use cases.

|
Setting | Default | Description
|
|||
|
|
:--- | :--- | :---
|
|||
|
|
`plugins.replication.indices.recovery.chunk_size` | 1MB | The chunk size requested by the follower cluster during file transfer. Specify the chunk size as a value and unit, for example, 10MB, 5KB.
|
|||
|
|
`plugins.replication.indices.recovery.parallel_chunks` | 5 | The number of file chunk requests that can be sent in parallel for each recovery.
|
|||
|
|
`plugins.replication.indices.recovery.request_timeout` | 60s | The amount of time to wait for individual network requests during the remote recovery process. A single action timeout can cause recovery to fail.
|
|||
|
|
`plugins.replication.indices.recovery.activity_timeout` | 5m | The amount of time to wait for recovery activity. If the leader cluster doesn't receive recovery requests from the follower for this amount of time, it closes the in-memory resources needed to supply data to the follower during recovery.
