The performance of a PostgreSQL database can be compromised by dead tuples, since they continue to occupy space and can lead to bloat. We provided an introduction to VACUUM and bloat in an earlier blog post. To know more about dead tuples and bloat, please read our previous blog post. Tuning Autovacuum in PostgreSQL.

There will be a short duration (tens of seconds) during which you will lose connectivity to your database due to the failover, but this can be overcome by having application-level retries.

Redis® is an in-memory database that provides blazingly fast performance. This makes it a compelling alternative to disk-based databases when performance is a concern. Redis returns a big list of database metrics when you run the info command on the Redis shell. This blog post lists the important database metrics to monitor.
