Rules and Guidelines for Relational Target Partitions

Rules and Guidelines for Relational Target Partitions

Consider the following rules and guidelines when you enable partitioning for a mapping that writes to a relational target:
  • The Data Integration Service uses one thread to write to the target, but can use multiple threads for the remaining mapping pipeline stages in the following situations:
    • The mapping writes to a relational target other than DB2 for LUW or Oracle.
    • The mapping uses a JDBC or ODBC connection to write to a DB2 for LUW or Oracle target.
  • Enable high precision for the mapping when a DB2 for LUW target table partition key is a decimal column. The Data Integration Service might fail the mapping when a partition key is a decimal column and you do not enable high precision for the mapping.
