I'm using Pig-HBaseStorage to load data from Hbase table,
I see the following option:
regex=regex Return rows with a rowKey that match this regex on KeyVal
Which means all rowkeys that match this regex expression will be returned.
My question is if there is a HBase table with rowkey of format:
And if regex expression is ex: partner_0123234_* [ usertype_timestamp_*]
Will a full table scan be done for the above regex where we specified the
Or, will Hbase be able to lookup rows for the above regex.
If a regex is of type *_012345_334576 [*_timestamp_userid], I agree, a full
table scan is required.
Any clarifications would be helpful.
