6.2 Walk-through

Just-in-Time compiler#

In QuestDB 6.2, our engineering team brings you a brand new JIT (Just-in-Time) compiler as a part of the SQL engine. The compiler aims to significantly improve the execution time for queries with simple arithmetic expressions used to filter your data.

It took us 11,000+ lines of code, 250+ commits, and many cups of coffee to ship this, and we've documented the story behind it in a blog post.
