 - `exclude_tables` - databases to __exclude__, string or list. If same table matches `tables` and `exclude_tables`, exclude has higher priority.
 - `log_level` - log level, default is `info`, you can set to `debug` to get maximum information (allowed values are `debug`, `info`, `warning`, `error`, `critical`)
 - `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.
