public TableDescriptorBuilder.ModifyableTableDescriptor setRegionMemStoreReplication(boolean memstoreReplication)
```
    Enable or Disable the memstore replication from the primary region to the replicas. The replication will be used only for meta operations (e.g. flush, compaction, ...)
    
    Parameters:
    
    memstoreReplication - true if the new data written to the primary region should be replicated. false if the secondaries can tollerate to have new data only when the primary flushes the memstore.
