Ted Yu commented on HBASE-7503:
-------------------------------
{code}
+ for (final Get get : gets) {
+ Integer startKeyIndex = null;
+ // Search which region this get is related to by comparing start and end
keys.
+ for (int i = 0; i < startEndKeys.getFirst().length; ++i) {
{code}
When the number of Get's is high, the above nested loop is not efficient.
Sergey suggested sorting the Get's so that you can traverse sorted Get's and
startEndKeys in tandem.
Can you do that ?
Thanks
