Jerry He commented on HBASE-14928:
----------------------------------
I am coping my comment in the mailing to here:
There seems to be a change in the way the url table/rowkey* is executed on
the Rest gateway.
in pre-0.96, we set the startKey = rowkey and endKey = rowkey + one byte of 255
on Rest gateway in the Scan sent to the servers.
In the newer versions, table/rowkey* seems to treated with a prefixFilter.
This may explain why you are seeing slower response.
> Start row should be set for query through HBase REST gateway involving
> globbing option

> As Ben Sutton reported in the thread, Slow response on HBase REST api using
> globbing option, query through the Rest API with a globbing option i.e.
> http://<HBase_Rest>:<HBase_Rest_Port>/table/key\* executes extremely slowly.
> Jerry He pointed out that PrefixFilter is used for query involving globbing
> option.
> This issue is to fix this bug by setting start row for such queries.
