We are glad to give you Version 9.4 of BaseX, our XML framework, database system and XQuery 3.1 processor:

https://basex.org/

We have focused on rewriting and optimizing complex XQuery code and speeding up your RESTXQ apps:

WEB APPLICATIONS

• DBA: support for millions of log entries
• LOGTRACE option: write trace output to logs or STDERR
• rest:init: Full or partial initialization of RESTXQ cache
• basexhttp: register job services

GUI

• result view: show number of results and result size
• Shift F4-F7: toggle search options (case, regeex, ..)
• Ctrl-Shift-B: jump to matching bracket

XQUERY LOCKING

• single lock option for reading and updating queries
• Java bindings: annotation added for updating functions

XQUERY FUNCTIONS

• convenience functions: json:doc, csv:doc, html:doc
• element names: convert:encode-key, convert:decode-key
• jobs:eval: option added for writing log entries
• session module: only create new sessions if required

XQUERY PERFORMANCE

• boolean comparisons: flatten nested expressions
• boolean expressions: merge conjunctions
• comparisons: simplify operands with if expression
• database functions: always open at compile time
• databases: propagate to more expressions at compile time
• filters: inline context for single items
• filters: rewrite to simple maps
• FLWOR: inline where clauses into let clauses
• FLWOR: merge last with return clause, rewrite to simple map
• FLWOR: rewrite "return if ..." to "where ... return"
• fn:for-each, fn:filter: rewrite to FLWORs and filters
• if expression, EBV tests: simplify boolean tests
• lists, sets, logical expressions: flatten expressions
• lists: rewrite to union expressions
• logical expressions: apply more boolean algebra rules
• paths: remove redundant predicates
• predicates with name functions: rewrite to name tests
• predicates: merge expressions, discard redundant tests
• predicates: remove of superfluous and redundant tests
• set expressions: merge operands
• simple map: inline cast expressions
• simple maps: faster evaluation
• simple maps: merge operands
• simple maps: rewrite to paths, optimize for index access
• switch: rewrite to if expression
• types: skip redundant checks, promotions and conversions

For a more comprehensive list of added and updated features, check out our documentation (docs.basex.org) and check out the GitHub issues (github.com/BaseXdb/basex/issues).

Have fun, Your BaseX Team
