The code is back to the database with Oracle MLE (GraalVM)
summary
Demonstrates Oracle Labs integrating GraalVM polyglot in-database so JavaScript and Python can run inside Oracle/MySQL, with a Docker beta that stores code as DB objects. Benchmarks move $1 across 300,000 accounts, $1 transfers: one SQL statement uses about 3 seconds CPU, equivalent PL/SQL loop costs ~40 seconds CPU due to context switches, and a client‑side JavaScript approach is slower still. Beta runs the polyglot engine in-process to avoid client/server switches but currently has extra callback overhead to optimize.
