Compaction

name	type	description
compaction.redzone	int	To create a new redzone, write a percent value into compaction namespace.
compaction.redzone.mode	int	Set compaction mode. Mode 1: branch-less mode (strict 2-level storage), 2: checkpoint, 3: branch + compaction (default).
compaction.redzone.compact_wm	int	Compaction operation starts when a number of node branches reaches this watermark. Cant be less than two.
compaction.redzone.compact_mode	int	Set read-intensive or write-intensive compaction strategy mode. 0 - by number of branches, 1 - by temperature.
compaction.redzone.branch_prio	int	Priority of branch operation. Priority is measured by a maximum number of executing workers.
compaction.redzone.branch_wm	int	Branch operation starts when a size of in-memory key index reaches this watermark value. Measured in bytes.
compaction.redzone.branch_age	int	Branch operation automatically starts when it detects that a node in-memory key index has not been updated in a branch_age number of seconds.
compaction.redzone.branch_age_period	int	Scheduler starts scanning for aged node in-memory index every branch_age_period seconds.
compaction.redzone.branch_age_wm	int	This watermark value defines lower bound of in-memory index key size which is being checked during branch_age operation. Measured in bytes.
compaction.redzone.anticache_period	int	Check for anti-cache node election every anticache_period seconds.
compaction.redzone.backup_prio	int	Priority of backup operation. Priority is measured by a maximum number of executing workers.
compaction.redzone.gc_wm	int	Garbage collection starts when watermark value reaches a certain percent of duplicates. When this value reaches a compaction, operation is scheduled.
compaction.redzone.gc_db_prio	int	Priority of a database async close/drop operation.
compaction.redzone.gc_prio	int	Priority of gc operation. Priority is measured by a maximum number of executing workers.
compaction.redzone.gc_period	int	Check for a gc every gc_period seconds.
compaction.redzone.lru_prio	int	Priority of LRU operation. Priority is measured by a maximum number of executing workers.
compaction.redzone.lru_period	int	Run LRU scheduler every lru_period seconds.
compaction.redzone.async	int	Asynchronous thread work mode: 1 - reserve thread, 2 - do not reserve thread.
