Optimize Relational Databases for Partitioning

Optimize Relational Databases for Partitioning

When a mapping that is enabled for partitioning reads from or writes to an IBM DB2 for LUW or an Oracle relational database, the Data Integration Service can use multiple threads to read the relational source or to write to the relational target.
To optimize performance when using multiple threads to read from or write to a DB2 for LUW or Oracle relational database, you can partition the source and target tables.
If a mapping reads from or writes to a relational database other than DB2 for LUW or Oracle, the Data Integration Service uses one reader thread or one writer thread.
