I would argue the opposite, distributed databases are much easier to operate at large scale. Truly online distributed DDL, at least in TIDB, strong consistency etc. People who bang on about Postgres replication have rarely setup replication in Postgres themselves and that too in the 100a of Pb scale. MySQL replication works well and can be scaled more easily (relative to Postgres) but has its own problems. eg., DDL is still a nightmare, lag is a real problem, usually masked by async replication. But then eventual consistency makes the application developers life more complicated. |
