Joel Bernstein edited comment on SOLR-8593 at 3/1/17 3:56 PM: -------------------------------------------------------------- The backport is turning out be trickier then I thought. The reason is that jira/solr-8593 has lots of master commits in it that are not in branch_6x. So merging is not going to work. Also getting an isolated list of the 80+ commits done in jira/solr-8593 for the Calcite integration is tricky because the original pull request is closed. Creating a new pull request against branch_6x includes all the master commits. So I'm looking at ways to isolate all the commits to cherry-pick. was (Author: joel.bernstein): The backport is turning out be trickier then I thought.

It was > nicely split off from the larger Presto project and it did everything that > was needed for the initial implementation. > Phase two of the SQL work though will require an optimizer. Here is where > Apache Calcite comes into play. It has a battle tested cost based optimizer > and has been integrated into Apache Drill and Hive. > This work can begin in trunk following the 6.0 release. The final query plans > will continue to be translated to Streaming API objects (TupleStreams), so > continued work on the JDBC driver should plug in nicely with the Calcite work. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
