Olga Natkovich resolved PIG-7. ------------------------------ Resolution: Fixed resolved with types branch > Optimize execution of algebraic functions > ----------------------------------------- > > Key: PIG-7 > URL: https://issues.apache.org/jira/browse/PIG-7 > Project: Pig > Issue Type: Improvement > Components: impl > Reporter: Olga Natkovich > Assignee: Alan Gates > Attachments: combiner.patch, combiner2.patch, combiner3.patch, > pig7.patch > > > Algebraic are functions that can be computed incrementally like count(X), > SUM(X), etc. They can be computed effciently by doing the first level > computation using hadoop combiner. This can give a significant (2-3x) speedup > for many aggregation queries. > Several users asked us for this feature so it is pretty high priority. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
