Hi all, we have a (very basic) custom query DSL for OLAP type queries and are investigating whether we can replace and improve on our current execution engine using calcite.
We believe using the RelBuilder would be a much nicer way to go from our custom query format to actual DB queries (while offering many potential benefits - planning process etc. - in the future). That said, we’ve run into a small issue: the “scan” method only accepts a String as a table identifier, meaning that we can’t specify a table of a sub schema (“db1”.”my_table”). Since RelOptSchema.getTableForMember accepts a list of Strings for this case we’re wondering whether a) there is a reason for only accepting a String (there is a comment in RelOptSchema.getTableForMember stating that “names.length is only greater than 1 for queries originating from JDBC”) b) scan could be overloaded to accept a List of Strings as well (in which case we’re happy to make that change) Cheers, Michael
