Class TestRegionIncrement

java.lang.Object

org.apache.hadoop.hbase.regionserver.TestRegionIncrement

public class TestRegionIncrement
extends Object

Increments with some concurrency against a region to ensure we get the right answer. Test is parameterized to run the fast and slow path increments; if fast, HRegion.INCREMENT_FAST_BUT_NARROW_CONSISTENCY_KEY is true.

There is similar test up in TestAtomicOperation. It does a test where it has 100 threads doing increments across two column families all on one row and the increments are connected to prove atomicity on row.
