# Variant Inverted-Index Cast Pushdown Compatibility Rules The final compatible cast rules for variant inverted-index pushdown are intentionally restricted to: - Exact same type after nullable removal. - Integer widening: `TINYINT -> SMALLINT -> INT -> BIGINT -> LARGEINT` - `FLOAT -> DOUBLE` - `CHAR/VARCHAR/STRING` compatibility, since the inverted-index string query path uses the same byte representation for all string primitive types. - ARRAY pushdown only for exact array type matches. In addition, the query literal is now normalized to the segment storage type before building the inverted-index query value, so compatible casts use the same encoded representation as the stored index data. -- This is an automated message from the Apache Git Service.
