Subject [jira] Commented: (PIG-1197) TextLoader should be updated to match changes to PigStorage

Dmitriy V. Ryaboy commented on PIG-1197:
----------------------------------------

I know you guys feel strongly about not adding anything but bug-fixes into 0.6 at this point,
but I would love for this to make it in. It's a huge performance boost, and people use TextLoader
a lot.

Agreed that it doesn't really need to go into 0.7 if we are hoping to get 966 completed for
that release.

> In 0.6 PigStorage was changed to use LineRecordReader to parse lines out of its stream
instead of doing the parsing itself.  This resulted in about a 30% speed up in parsing time.
 TextLoader should be changed to use LineRecordReader in the same way to benefit from the
same speed up.
