Commit Points Overview

Commit Points Overview

A commit interval is the interval at which the Integration Service commits data to targets during a session. The commit point can be a factor of the commit interval, the commit interval type, and the size of the buffer blocks. The commit interval is the number of rows you want to use as a basis for the commit point. The commit interval type is the type of rows that you want to use as a basis for the commit point. You can choose between the following commit types:
  • Target-based commit.
    The Integration Service commits data based on the number of target rows and the key constraints on the target table. The commit point also depends on the buffer block size, the commit interval, and the Integration Service configuration for writer timeout.
  • Source-based commit.
    The Integration Service commits data based on the number of source rows. The commit point is the commit interval you configure in the session properties.
  • User-defined commit.
    The Integration Service commits data based on transactions defined in the mapping properties. You can also configure some commit and rollback options in the session properties.
Source-based and user-defined commit sessions have partitioning restrictions. If you configure a session with multiple partitions to use source-based or user-defined commit, you can choose pass-through partitioning at certain partition points in a pipeline.
