Tomorrow I'll publish a deep dive on PostgreSQL’s optimizer and how Postgres decides how to run your SQL. If you only read one of my Postgres posts, make it this one. Great for anyone who writes SQL. 👉 https://t.co/FpFw3UZ6cz

@ishaysw I know the names are confusing. I think you have "text indexes" in mind ↙️. The Lucene-based ones were first implemented in Atlas, but they have been added recently to the community edition ↘️ (currently in preview) https://t.co/OGQFS5qtb1

Some people complain that there's no 'eventual', 'strong', or 'strict' consistency, and it's either consistent or not. But there are always trade-offs between performance and failures with low probability. What about 'paranoid' consistency to prevent dirty reads?
