Overview
Note
Note
- All the nodes will apply the Frontend patch/set wherever the Postgresql and OpenSearch changes will be used to only one cluster node.
- After patching/setting any configuration, certain services will restart. The time required for your services to regain stability may vary depending on the amount of data stored in your system.
Warning
- For certificate rotation, don’t use
config patch. Instead, thecert-rotatecommand can be used. To know more about certificate rotation, click here - While patching the same from the provision host, structures such as TLS from the OpenSearch configuration .toml file and SSL from the PostgreSQL configuration toml file will be ignored.

How to patch max shards per node for opensearch
To configure OpenSearch max shard per node, create a TOML file that contains the partial configuration below. Change max_shards_per_node as needed, and then run command to apply change.
[cluster]
max_shards_per_node = "2000"
