Changes in HeatWave 8.0.30-u1 (2022-09-06, General Availability)

Functionality Added or Changed

• HeatWave now supports the ABS(), POWER(), and SIGN() mathematical functions.

• HeatWave now supports the GROUP_CONCAT() aggregation function with variable-length (VARLEN) string columns.

• Change propagation memory management was enhanced to improve HeatWave shutdown time.

• Query performance was optimized for compressed data. Decompression of data that is queried but does not participate in filter evaluation is delayed until after a filter is applied. With this optimization, decompression is avoided entirely for data that is filtered out.
