Enclosing class:

MemStoreCompactionStrategy

public static enum MemStoreCompactionStrategy.Action
extends Enum<MemStoreCompactionStrategy.Action>

Types of actions to be done on the pipeline upon MemStoreCompaction invocation. Note that every value covers the previous ones, i.e. if MERGE is the action it implies that the youngest segment is going to be flatten anyway.
