Relational Sources on Hadoop

Relational Sources on Hadoop

You can run mappings with relational sources on the Blaze engine.
The Data Integration Service does not run pre-mapping SQL commands or post-mapping SQL commands against relational sources. You cannot validate and run a mapping with PreSQL or PostSQL properties for a relational source in a Hadoop environment.
The Data Integration Service can use multiple partitions to read from the following relational sources:
  • IBM DB2
  • Oracle
