 - `optimize_interval` - interval (seconds) between automatic `OPTIMIZE table FINAL` calls. Default 86400 (1 day). This is required to perform all merges guaranteed and avoid increasing of used storage and decreasing performance.
 - `auto_restart_interval` - interval (seconds) between automatic db_replicator restart. Default 3600 (1 hour). This is done to reduce memory usage.
 - `indexes` - you may want to add some indexes to accelerate performance, eg. ngram index for full-test search, etc. To apply indexes you need to start replication from scratch.
