Database performance: Postgres vs. MySQL
Kestra supports Postgres and MySQL, among other databases; our internal benchmarks showed that Postgres performed much better than MySQL when running Kestra. We therefore generally recommend running Kestra in production with Postgres. During our benchmarks, Postgres sustains 4,000 executions/min with a latency of 370 ms for our typical flows, and a latency of around 130 ms for a single launch. MySQL, for its part, cannot even sustain 1,000 executions/min, and has a latency of around 160 ms for a single…
