Andrew Purtell commented on HBASE-1807:
---------------------------------------
One minor optimization:
{code}
public ReturnCode filterKeyValue(KeyValue v) {
- if (doCompare(rowCompareOp, rowComparator, v.getBuffer(),
- v.getKeyOffset(), v.getKeyLength())) {
- return ReturnCode.NEXT_ROW;
}
ReturnCode rc = ReturnCode.INCLUDE;
if (doCompare(familyCompareOp, familyComparator, v.getBuffer(),
v.getFamilyOffset(), v.getFamilyLength())) {
rc = ReturnCode.SKIP;
}
if (rc == ReturnCode.INCLUDE) {
if (v.getQualifierLength() > 0) {
if (doCompare(qualifierCompareOp, qualifierComparator, v.getBuffer(),
v.getQualifierOffset(), v.getQualifierLength())) {
rc = ReturnCode.SKIP;
}
}
}
return rc;
}
{code}
since I just realized that filterKeyValue is only called if filterRowKey passes.

---------------------------------------
Filtering on family was the specific request. ("Is there any ways to retrieve values whose columns match specific regular expression?") At least that is my interpretation of that wording.

Patch looks fine. Do these filters need to be added to HBaseObjectWritable? Pity there are no tests. You going to add these JG?

---------------------------------
Sorry for the delay.
I mean columns qualifiers.Since column families are pre-defined in table schema, the ability to match column qualifiers by regex may be more useful in reality.

Jonathan Gray commented on HBASE-1807:
--------------------------------------
Does everyone think it's worth it / makes sense to include family in here? Andrew's patch includes it but are things like regex/prefix valuable on family? We should discourage people from filtering families in/out using filters as opening them in the first place is costly... everyone should use the API directly.

--------------------------------------
This patch looks excellent, Andrew!
I'm working on some other filters right now, but could probably work them into the key filter (regex, for example, would just be a WritableByteArrayComparable?)
We need tests and should probably put some usage documentation in the filter package overview. I'm planning on spending time with filters today so if you don't have time let me know and I can build on your patch today.
