Joel Bernstein commented on SOLR-8593: -------------------------------------- I was thinking about merging https://github.com/apache/lucene-solr/tree/jira/solr-8593 into branch_6x rather then cherry picking from master. There is one commit that will need to be reverted because it's only valid in master, but that should fairly easy to do I think. > Integrate Apache Calcite into the SQLHandler > -------------------------------------------- > > Key: SOLR-8593 > URL: https://issues.apache.org/jira/browse/SOLR-8593 > Project: Solr > Issue Type: Improvement > Components: Parallel SQL > Reporter: Joel Bernstein > Assignee: Joel Bernstein > Fix For: 6.5, master (7.0) > > Attachments: SOLR-8593.patch, SOLR-8593.patch, SOLR-8593.patch > > > The Presto SQL Parser was perfect for phase one of the SQLHandler. 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
