Pressenna closed CALCITE-3219. ------------------------------ Resolution: Abandoned closing for now as not relevant ... > Allow finer control over which expressions get expanded in SqlToRelConverter > ---------------------------------------------------------------------------- > > Key: CALCITE-3219 > URL: https://issues.apache.org/jira/browse/CALCITE-3219 > Project: Calcite > Issue Type: Improvement > Reporter: Pressenna > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Currently one can control if sub-query expansion happens via > SqlToRelConverter.Config.isExpand(). This flag is global to the query and > causes expansion of all supported expression types. For some systems it is > required that one can dynamically narrow the set of expressions that should > be expanded. > In order to allow this, I would propose a new setter with a default > implementation that returns the above flag. > {code} > // a BiPredicate in order to pass both the original query and the expression > in question for expansion > java.util.function.BiPredicate<SqlNode, SqlNode> > SqlToRelConverter.Config.getExpandPredicate() > {code} > If this is OK, I would provide a PR with the relevant changes. -- This message was sent by Atlassian Jira (v8.3.4#803005)
