主旨： [ADMIN] How do you manage cluster replication and failover ?
Hello,
We are currently trying to setup a multi hosts databases cluster with goals:
* replication (no data-loss is "required", replication timing do not needs to be instant)
* failover
* load-balancing (bonus)
We tried:
* synchronious replication (pgpool replication mode) + load-balancing (pgpool) : very interesing as we can theorically failover on any node at any moment. But even after several configuraation tweeks, we never succeed getting good write performance.
* asynchronious replication (postgres 9.6 streaming replication) : good write performance, good replication timings (< 1 second for small transactions). We could loadbalance select requests using pgpool.
How do you manage your postgresql clusters ? Do you use pgpool ? pgbouncer ? other ?
How do you manage to single access point ? usign pgpool ? pgbouncer ?
Do you use streaming replication ? WAL archiving ? How do you handle to automatic failover ?
Robin
