SQL Metadata updates

Hey all,

How does the SQL metadata get updated when new segments are added? We’re having an issue where metrics and dimensions are available for querying via the native query API but not available via SQL. We used hadoop batch ingestion to ingest one set of metrics and dimensions, and then ingested additional metrics and dimensions for the same time interval via native ingestion, and now the new columns are unavailable via SQL. Is there a way to force a refresh of the INFORMATION_SCHEMA tables?
