## Description Adding validation for json_extract_key and json_extract_scalar functions during sql compilation phase to avoid empty response If user mistakenly put double quote on a the json key argument, say `jsonExtractScalar(myMapStr,"$.k1", 'STRING')`, then query parser recognizes the second argument `$.k1` as an identifier. Then during segment pruning phase, the DataSchemaSegmentPruner prunes all the segments as there is no column matches `$.k1`. Then user will get an empty results. Adding a function validation method during compilation time will allow us to find out the expression type mismatch then error out earlier and direct more comprehensive errors and guides to users. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
