Hi all:

First time I see the CHECKSUM clause, and I have a few questions, already checked the documentation and yet I don't quite understand:

- WHAT IS IT ?

- Does it have an impact on performance ? How much ?

- The percentages that the documentation shows, what do they mean exactly ? I just don't get it.

     CREATE SET TABLE dwh.table_a,
          NO FALLBACK ,
          NO BEFORE JOURNAL,
          NO AFTER JOURNAL,
          CHECKSUM = DEFAULT
          ..

Cheers,

Cesar
