New data tables are non-Pega formatted
Valid from Pega Version 7.4
All new data tables are created as non-Pega formatted tables, that is, they do not contain a BLOB column, a pzInsKey column, or a pxObjClass column. The table's primary key will be the key that you specify, not pzInsKey. Data table construction was changed to improve performance of the Obj-Save method during batch operations, such as data imports, to make it easier to replace the table with an external system of record and to make it easier to share data among applications.
