Uses of RegionCoprocessor in org.apache.hadoop.hbase.coprocessor.example
Classes in org.apache.hadoop.hbase.coprocessor.example that implement RegionCoprocessorModifier and TypeClassDescriptionclassDefines a protocol to delete data in bulk based on a scan.classAn example coprocessor that collects some metrics to demonstrate the usage of exporting custom metrics from the coprocessor.(package private) classclassCoprocessor endpoint to refresh HFiles on replica.classSample coprocessor endpoint exposing a Service interface for counting rows and key values.classA RegionObserver which modifies incoming Scan requests to include additional columns than what the user actually requested.classThis RegionObserver replaces the values of Puts from one value to another on compaction.classAn example for implementing a counter that reads is much less than writes, i.e, write heavy.classThis is an example showing how a RegionObserver could be configured via ZooKeeper in order to control a Region compaction, flush, and scan policy. -
