Quickest Mapping Of Java Enums
Description: This application uses EnumType.ORDINAL and EnumType.STRING for mapping Java enum type to database. As a rule of thumb, strive to keep the data types as small as possible (e.g., for EnumType.ORDINAL use TINYINT/SMALLINT, while for EnumType.STRING use VARCHAR(max_needed_bytes)). Relying on EnumType.ORDINAL should be more efficient but is less expressive than EnumType.STRING.
Key points:
- strive for smallest data types (e.g., for
EnumType.ORDINALset@Column(columnDefinition = "TINYINT"))
