Hi all--
I was reading the source code for Pig HBaseStorage loadfunc/storefunc recently.
It accepts arguments such as -gte and -lt for scanning ranges of rows;
however, it implements them by adding a RowFilter. Something that
basically boils down to ...
scan = new Scan();
gte_ =
Bytes.toBytesBinary(Utils.slashisize(configuredOptions_.getOptionValue("gte")));
scan.setFilter(new RowFilter(CompareOp.GREATOR_OR_EQUAL, new
BinaryComparator(gte_)));
How does this compare (in terms of equivalence and performance) to
setting startRow on Scan .. such as ..
scan = new Scan();
scan.setStartRow(Bytes.toBytesBinary(Utils.slashisize(configuredOptions_.getOptionValue("gte")));
Thanks.
