We are more than pleased to announce version 9.2 of BaseX, our XML framework, database system and XQuery 3.1 processor.

This time, we have put a special focus on performance improvements:

XQuery Performance

  • comparisons will more often be rewritten to hash joins
  • optimized access to subsequences and single sequence items
  • consistent propagation of static types to evaluation results
  • improved static typing of function items (maps, arrays)
  • more aggressive pre-evaluation at compile time

Storage Performance

  • large databases will be opened faster
  • regular storage offset will be computed at runtime

  • Archive Module: archive:create-from, new options

  • Profiling Module: new functions (prof:gc, prof:runtime)
  • Validation Module: assign XSD validation features
  • WebSocket Module: query scheduling via ws:eval
  • Utility Module: various new helper functions
  • XSLT Module: support for XML Catalogs (thank you Liam)

New Options
