Seeing dramatic differences in Gandiva processing time during filter operations for queries with a LIKE filter on a character field with a reserved character (-,/& etc). The version with a reserved character in the string is considerably slower than a similar filter without a reserved character. For patterns like %abc% and %ab-c%, the latter wasn't being optimized to become an is_substr expression because of the regex used to identify those cases. -- This is an automated message from the Apache Git Service.
