Patch will be submitted under Pig-1772. > Need to document when combiner is used > -------------------------------------- > > Key: PIG-1790 > URL: https://issues.apache.org/jira/browse/PIG-1790 > Project: Pig > Issue Type: Improvement > Components: documentation > Reporter: Olga Natkovich > Assignee: Corinne Chandel > Fix For: 0.9.0 > > > I serached through the documentation but could not find a section that > describes the cases under which combiner is used. Since combiner has such a > significant impact on query performance, I think it is important to add this > information. Also, with 0.9 we are expending combiner usage so having > documentation would be useful for that as well. > Here are the JIRAs for combiner use slated for 0.9: > https://issues.apache.org/jira/browse/PIG-750 > https://issues.apache.org/jira/browse/PIG-490 > https://issues.apache.org/jira/browse/PIG-946 > https://issues.apache.org/jira/browse/PIG-1735 -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
