## What changed? Both our PostgreSQL and MySQL database backends will now automatically reconnect to the database when certain errors occur: all errors chosen have been experienced when testing this behavior through an AWS Aurora RDS failover of either MySQL or PostgreSQL. For both backends we will reconnect when we see: - `ECONNRESET` - `ECONNABORTED` - `ECONNREFUSED` - `io.EOF` - `io.ErrUnexpectedEOF` - `database/sql/driver.ErrBadConn` for postgres we will also reconnect on the following SQLStates: - `25006` read-only transaction - `57P03` cannot connect now - `0A000` feature not supported, but ONLY when the message is `cannot set transaction read-write mode during recovery` for mysql we will also reconnect when we see the following error codes: - `1040` too many connections - `1792` read-only transaction (SQLstate `25006`) - `1836` running in read-only mode This logic is easily extensible should we discover more failure modes over time ## Why? We've had multiple community reports of Temporal problems during RDS failover. One part of this is the fact that we wouldn't necessarily reconnect; we were at the whims of our chosen SQL abstraction's connection pooling logic. ## How did you test it? I manually tested this functionality in the presence of repeated RDS failovers: - [x] postgres12 plugin with pq driver - [x] postgres12 plugin with pgx driver - [x] mysql plugin Automated testing will be added to our regular testing pipelines once our infrastructure friends have added the support I need (it's in progress) ## Potential risks We're concerned there's a correctness issue in our PostgreSQL backend that's related to our behavior during an RDS failover. If we merge this before I figure out what's going on, we could hide the issue and make it harder to reproduce. ## Documentation N/A ## Is hotfix candidate? Yes?
