JSON type alias is insufficiently compatible

Details

    • Bug
    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed
    • 10.2.7
    • 10.2.8
    • Data types, JSON
    • None

    Description

      Now it maps to TEXT. It'd be more compatible to map it to

        LONGTEXT CHARACTER SET utf8mb4 CHECK(JSON_VALID(col))

      But auto-adding a constraint is questionable. An unexpected constraint in the table definition, performance implications, strange errors if one manually specifies some constraint for this column.
