Documentation
Definition
Frequency of database commits during the update phase of the conversion.
Use
During the selection phase of the conversion the data is written to the special cluster table. In update phase this data is read from this cluster table, converted and written back to the original database table. To commit the changes in the database a COMMIT command has to be issued. This value controls how often this happens (after how many bytes are read from the cluster table since the last commit).

Use
This value can have impact on the performance. The greater the value, the more seldom the data has to be commited and the less I/O activity is needed (commits are quite I/O-intensive). On the other hand seldom commits imply long transactions and the longer the transaction is the more undo / rollback buffer space is used, which can even lead the conversion program to dump.
