Subject [jira] [Commented] (PIG-2886) Add Scan TimeRange to HBaseStorage
Date Sun, 02 Sep 2012 22:02:08 GMT

Dmitriy V. Ryaboy commented on PIG-2886:
----------------------------------------

Urk.. git patch. You need to generate it with 'git diff --no-prefix' otherwise we can't apply
it. I mean, we can, and I did, but for next time, --no-prefix makes life easier :).

> I have a client that wants to use pig.  They are using MR now.  They can't use PIG right
now because they only want to fetch the last day's worth of data in HBase.  A filter with
time range would require reading all the HStore files.  If we hold major compaction until
after the fetch and use Scan Time Range we only need to read very little in compression.
