Synchronizing Specified Indexes
Synchronize a single index.
The request URL and request body parameters are as follows:

Parameter |
Description |
---|---|
remote_cluster |
Name of the primary cluster. The default name is leader1. You can change the name by configuring the primary cluster information. |
remote_index |
Name of the index to be synchronized in the primary cluster |
local_index |
Name of the index being synchronized to the secondary cluster |
settings |

After the synchronization function is enabled, indexes in the secondary cluster become read-only and are periodically synchronized with indexes in the primary cluster.
The following are two examples:
- Synchronize a single index from the primary cluster to the secondary cluster.
PUT start_remote_sync { "remote_cluster": "leader1", "remote_index": "data1_leader", "local_index": "data1_follower" }
- Synchronize a single index from the primary cluster to the secondary cluster and modify the index configurations.
PUT start_remote_sync { "remote_cluster": "leader1", "remote_index": "data1_leader", "local_index": "data1_follower", "settings": { "number_of_replicas": 4 } }
The following index configurations cannot be modified:
- number_of_shards
- version.created
- uuid
- creation_date
- soft_deletes.enabled
