Many organizations also find it useful to use an open source observability tool, such as OpenTelemetry. Use SLAs, SLOs, and SLIs as performance benchmarks for newly migrated microservices. With real-time observability, teams can easily plan their migration and fine-tune performance as they migrate microservices.

If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? To be fair, that is also true with PostgreSQL; it hasn’t been tuned either, and it, too, can also perform much better.

Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. It is primarily the responsibility of the database administrator or developer to tune PostgreSQL according to their system’s workload. Some applications perform better by tuning a parameter and some don’t. wal_buffers. Conclusion.
