Replication is now available for RealTime indexes and works in the same way as for percolate indexes.
Currently INSERT / REPLACE / DELETE and UPDATE statements can be used on replicated RT indexes. ALTER and ATTACH statements support will be added in future releases and OPTIMIZE only perform the optimization locally.
Replication now supports multiple statement transactions, previously only single statement commits were available.
Internally, we refactored how threads responsible for different jobs (like flushing) are woke up. The new changes should translated in lower idle CPU usage.
A new directive ‘icu_data_dir‘ is available for specifying the ICU files when ICU is manually compiled.
SHOW VARIABLES statement support
LIKE 'pattern' clause.
For percolate indexes, INSERT can now accept multiple stored query documents, before INSERT accepted only one stored query document per statement.
Configuration directives that express time can accept string time expressions. For example
rt_flush_period = 3600 can be rewritten as
rt_flush_period = 60m or
rt_flush_period = 1h.
Snippet paths are now jailed inside the scope of snippets_file_prefix even if paths are relative.
Support for RLP processor dropped. All rlp_* configuration directives removed.
UPDATE statements don’t support anymore updating the value of document IDs.
A number of fixes are included in this release, to highlight a few:
- 58dcbb77 fixes #246 undefined sigmask in indexer
- 44757711 fixes hash of clusters lock in replication
- f0472223 fix defects in concat and group_concat
