We are happy to announce the release of Rumble 1.11.0 "Banyan Tree" beta.

It is a free, open source JSONiq engine (JSON-tuned cousin of XQuery) that can process sequences with billions of items, and can be downloaded as a jar from


Some new features compared to the last announced version (1.9):

- Static typing following the XQuery standard (activated with --static-typing yes on the CLI)
- support for floats
- max/min/avg/sum are now pushed down to Spark for large sequences (like count)
- pushdown of simple position lookups

- and many many bugfixes and W3C compatibility improvements, which is our current focus (many based on the XQuery 3.0/3.1 test suite)
