I’ll be discussing Postgres MVCC this Friday at PGConf Silicon Valley. Discover why MVCC can be challenging in Postgres and learn how to optimize it. Don't miss out!

Everyone loves PostgreSQL . But as much as we love Postgres, certain aspects are not that great. We believe Postgres MVCC(multi-version concurrency control) implementation is the worst among other widely used DBMSs. To learn more, check out this blog!

Somebody is emailing people with fake OtterTune interview invitations. We do not know who it is or how to stop them. Going forward, unless the invitation email comes from me via Lever with a Wu Tang Clan quote in it, you should unfortunately assume that it is a phishing scam.

In our previous blog, Andy Pavlo (@andypavlo.bsky.social) and I discussed the problems caused by the MVCC implementation in #PostgreSQL, such as version copying, table bloat, and index maintenance overhead. This subsequent article will explore ways to optimize PostgreSQL for each problem.

I'm to sad to announce that OtterTune is officially dead. Our service is shutdown and we let everyone go today (1mo notice). I can't got into details of what happened but we got screwed over by a PE Postgres company on an acquisition offer. ottertune.com/index.html
