Subject [jira] Updated: (PIG-531) Way for explain to show 1 plan at a time
Date Thu, 28 Jan 2010 00:22:34 GMT

Viraj Bhat updated PIG-531:
---------------------------

    Fix Version/s: 0.5.0

Hi Olga,
 I think we have a way to handle it in multi-query optimization. Is it reasonable to close
this as fixed.

I see the following in the Multi-query document about explain:

http://wiki.apache.org/pig/PigMultiQueryPerformanceSpecification

explain [-out <path>] [-brief] [-dot] [-param <key>=<value>]* [-param_file
<filename>]* [-script <scriptname>] [<handle>]

> Several users complained that EXPLAIN output is too verbose and is hard to make sense
of.
> One way to improve the situation is to realize is that EXPLAIN actually contains several
plans: logical, physical, backend specific. So we can update EXPLAIN to allow to show a particular
plan. For instance
> EXPLAIN LOGICAL A;
> would show only logical plan.
