Bugs Fixed

  • Attribute promotion and demotion when restoring data to NDB tables using ndb_restore --restore_data with the --promote-attributes and --lossy-conversions options has been improved as follows:

    • Columns of types CHAR, and VARCHAR can now be promoted to BINARY and VARBINARY, and columns of the latter two types can be demoted to one of the first two.

      Note that converted character data is not checked to conform to any character set.

    • Any of the types CHAR, VARCHAR, BINARY, and VARBINARY can now be promoted to TEXT or BLOB.

      When performing such promotions, the only other sort of type conversion that can be performed at the same time is between character types and binary types.
