Lars Hofhansl updated HBASE-9711:
---------------------------------
Attachment: 9711-trunk.txt
Simple patch. Copying the bytes ahead of the String(...) only makes sense if
the compared portion is less than 1/2 of the passed byte[].
This is a simple patch. If I do not hear any objections I will commit this to
0.94+.
> Improve HBASE-9428 - avoid copying bytes for RegexFilter unless necessary

> Parent patch copies input for RegexFilter unconditionally.
> We should only do this if the KV portion into the passed byte[] is < 1/2 of
> the passed byte[]. Otherwise we waste cycles.
> Patch is trivial and will be coming momentarily.
