Add BitComparator for filtering
-------------------------------
Key: HBASE-3335
URL: https://issues.apache.org/jira/browse/HBASE-3335
Project: HBase
Issue Type: Improvement
Components: client
Affects Versions: 0.89.20100924
Reporter: Nathaniel Cook
Priority: Minor
There are many uses cases for setting bits flags and being able filter on those
seems like a good idea.
The BitComparator would take a byte[] and a bitwise operator for its
constructor. It would perform the bitwise operation on the column value bytes
with the specified byte[]. Then return whether the result was non-zero.
Only the CompareOp.EQUAL and CompareOp.NOT_EQUAL would make sense with this
comparator.
The binary bitwise operators that apply are AND, OR, and XOR.
