Hello,

How can we find that what partition method was used during an execution if the "Auto" Partition is used in the stages?

Thanks

Read the Job Score.

Or know the rules. Auto gives:

Round Robin if the link is from sequential to parallel or from parallel to sequential.

Same if the link is from parallel to parallel with the same degree of parallelism, or Round Robin otherwise.

Entire if the link is a reference input link to a Lookup stage.

Hash if the link is an input link to a stage that requires key-partitioned input.

DB2 if the link is an input link to a DB2/UDB Enterprise stage.
