Datatype Conversion

RAPCache and RAPStore subscribers attempt automatic datatype conversion if the datatypes are compatible and no loss of precision occurs.

Automatic datatype conversion occurs between the RDS datatypes used to transfer messages between the publisher and subscriber sides, and the database column datatypes used to store the information.
