> @alamb @jbonofre do InfluxDB and Dremio satisfy the assumptions here (dataset_schema will be populated if and only if the query of a prepared statement returns a result set)? I'm wondering if there might be systems that don't analyze the query at first and always omit the schema until actual execution Yes. However, I think all our queries return results (InfluxDB doesn't do DDL / DML using SQL -- there is an alternate write path) so this particular issue is unlikely to affect us Our system will actually analyze / plan the query twice -- once on the prepare and once when executing. While this is somewhat wasteful it allows us to remain stateless between requests -- This is an automated message from the Apache Git Service.
