Subinterfaces of Coprocessor in org.apache.hadoop.hbase.coprocessor

Modifier and Type	Interface and Description
interface	BulkLoadObserver Coprocessors implement this interface to observe and mediate bulk load operations.
interface	EndpointObserver Coprocessors implement this interface to observe and mediate endpoint invocations on a region.

interface	RegionObserver Coprocessors implement this interface to observe and mediate client actions on the region.
interface	RegionServerObserver
interface	WALObserver It's provided to have a way for coprocessors to observe, rewrite, or skip WALEdits as they are being written to the WAL.
