Hello,
I am new to PostgreSQL and having to migrate a Cassandra cluster to PostgreSQL.
Have a reasonable amount of experience with MySQL and use Master -> Master MySQL replication quite successfully.
I am trying to understand what configuration/option to pick for PostgreSQL that will provide the same or similar level of operational easy as the Cassandra cluster. What I mean by that is : Backups, Patching (rebooting nodes to patch)
With Cassandra any single node can be patched and rebooting without incurring downtime. This is also true with MySQL master->master replication, which we have fronted by a HAproxy reverse proxy (we can fail over between the two MySQL node, draining the connections as we do so and then patching and reboot).
I have found the following documentation:
https://www.postgresql.org/docs/current/different-replication-solutions.html
and have heard of “Traktor”, “pgEdge” and some other third-party tools.
My difficulty is that with very little knowledge of PostgreSQL I am having a hard time sorting through the various options and determining which are potential candidates for the kind of setup I am looking for (something approximating MySQL master->master replication).
Any advice or resources would be much appreciated.
Regards
