This PR implements the SQL component of the native unnest functionality in Druid. Unnest in SQL through Calcite has been implemented as a combination of Correlate (the comma join part) and Uncollect (the unnest part). Here we have introduced rules to handle unnest SQL queries on a table dimension, virtual column or a constant array and appropriate rels to convert them into Druid convention to translate correctly into native Druid queries. -- This is an automated message from the Apache Git Service.
