Uses of RegionCoprocessor in org.apache.hadoop.hbase.coprocessor
Modifier and TypeClassDescriptionclass
A coprocessor that collects metrics from meta table.(package private) class
class
This class implements atomic multi row transactions usingHRegion.mutateRowsWithLocks(Collection, Collection, long, long)
and Coprocessor endpoints. -
Uses of RegionCoprocessor in org.apache.hadoop.hbase.coprocessor.example
Modifier and TypeClassDescriptionclass
Defines a protocol to delete data in bulk based on a scan.class
An example coprocessor that collects some metrics to demonstrate the usage of exporting custom metrics from the coprocessor.(package private) class
class
Coprocessor endpoint to refresh HFiles on replica.class
Sample coprocessor endpoint exposing a Service interface for counting rows and key values.class
A RegionObserver which modifies incoming Scan requests to include additional columns than what the user actually requested.class
This RegionObserver replaces the values of Puts from one value to another on compaction.class
An example for implementing a counter that reads is much less than writes, i.e, write heavy.class
This is an example showing how a RegionObserver could be configured via ZooKeeper in order to control a Region compaction, flush, and scan policy. -
