Class SlotsSizeBasedCompactPolicy

java.lang.Object

com.exalead.mercury.mami.indexing.v10.AutoCompactPolicy

com.exalead.mercury.mami.indexing.v10.SlotsSizeBasedCompactPolicy

All Implemented Interfaces:

com.exalead.util.Checkable, java.io.Serializable

public class SlotsSizeBasedCompactPolicy
extends AutoCompactPolicy
implements com.exalead.util.Checkable, java.io.Serializable

Compaction policy based on size that produces slots with similar size.
When N consecutive slots have a size below targetSizeForCompactionMB, it performs a compaction if:

• N is at least minArity AND
• The N+1 slot makes the size above targetSizeForCompactionMB OR
• The size is above minSizeForCompactionMB
