Alan Gates updated PIG-777: --------------------------- Status: Open (was: Patch Available) Moving from patch available to open since the contributed patch has been committed and the JIRA is being held open to address other issues. > Code refactoring: Create optimization out of store/load post processing code > ---------------------------------------------------------------------------- > > Key: PIG-777 > URL: https://issues.apache.org/jira/browse/PIG-777 > Project: Pig > Issue Type: Improvement > Reporter: Gunther Hagleitner > Attachments: log_message.patch > > > The postProcessing method in the pig server checks whether a logical graph > contains stores to and loads from the same location. If so, it will either > connect the store and load, or optimize by throwing out the load and > connecting the store predecessor with the successor of the load. > Ideally the introduction of the store and load connection should happen in > the query compiler, while the optimization should then happen in an separate > optimizer step as part of the optimizer framework. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
