15.18. Release 0.112

General Changes

  • Fix incorrect handling of filters and limits in row_number() optimizer. This caused certain query shapes to produce incorrect results.
  • Fix non-string object arrays in JMX connector.

Hive Changes

  • Tables created using CREATE TABLE (not CREATE TABLE AS) had invalid metadata and were not readable.
  • Improve performance of IN and OR clauses when reading ORC data. Previously, the ranges for a column were always compacted into a single range before being passed to the reader, preventing the reader from taking full advantage of row skipping. The compaction only happens now if the number of ranges exceeds the hive.domain-compaction-threshold config property.
