## AI overview

Fivetran describes compiling SQLGlot, a pure Python SQL parser and transpiler, with mypyc to improve performance while retaining a pure Python option. The article covers design tradeoffs, packaging, compiler fixes, and optimizations, including reported speedups in parser, optimizer, and SQL generation workloads.

## Source excerpt

It has never been faster or easier to translate between different SQL dialects so that you can use different query engines.
