11.129. 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 rangebefore being passed to the reader, preventing the reader from taking fulladvantage of row skipping. The compaction only happens now if the number ofranges exceeds the hive.domain-compaction-threshold
config property.
