CCIndex merged with HBase 0.90.0 CCIndex is short for Complemental Clustering Index which used to support Multi-Dimensional Range Query on Non-primary key attributes in HBase. Codes of CCIndex are in the following two packages : org.apache.hadoop.hbase.client.ccindex org.apache.hadoop.hbase.regionserver.ccindex There is a test case of CCIndex : org.apache.hadoop.hbase.CCIndexTestCase.java The class named "MultiDimensionRangeQueryTest" is used to perform Multi-Dimensional Range Query. Users can use "sequentialWrite" to create a CCIndex with three indexes and use "clusterScan" to perform Queries. Further information please refer to the documents in doc file. Current status: Add a log system to ensure the data consistency. Reconstruct CCIndex based on the coprocessor framework.
