[jira] [Issue Comment Deleted] (FLINK-687) Add support for outer-joins
[ https://issues.apache.org/jira/browse/FLINK-687?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ricky Pogalz updated FLINK-687: --- Comment: was deleted (was: Hi, during the project course IMPRO3 at TU-Berlin we planned to work on this operator as a bigger task in the next weeks. Unfortunately, I just recognized that this parent issue is already assigned, but not the subtasks though. [~chiwanpark] Are you about to work on the sort-merge based outer join or is it okay for you if we take this issue? ) Add support for outer-joins --- Key: FLINK-687 URL: https://issues.apache.org/jira/browse/FLINK-687 Project: Flink Issue Type: New Feature Reporter: GitHub Import Assignee: Chiwan Park Priority: Minor Labels: github-import Fix For: pre-apache There are three types of outer-joins: - left outer, - right outer, and - full outer joins. An outer-join does not filter tuples of the outer-side that do not find a matching tuple on the other side. Instead, it is joined with a NULL value. Supporting outer-joins requires some modifications in the join execution strategies.

You can take this issue. :) I don't start work about the sort-merge based outer join. If there is a chance after the sort-merge based outer join, I would like to implement the hash-join based outer join.)
