Fine-tuning

• : maximum number of open connections to the Postgres database (default: unlimited)

The default connectionTimeout will work well in those cases where both kuma-cp and Postgres database are deployed in the same datacenter / cloud region.

maxOpenConnections

The more dataplanes join your meshes, the more connections to Postgres database Kuma might need to fetch configurations and update statuses.

However, if your Postgres database (e.g., as a service in the cloud) only permits a small number of concurrent connections, you will have to adjust Kuma configuration respectively.
