Description |
Identifies jobs featuring Hashed Files that do not read and write from the same stage. |
Issue
Using a Hashed file in the middle of a job flow serves as a point of synchronisation: the write operation on the inbound link completes before the read operation on the outbound link.
Where the read occurs from a different stage from the write, the conversion of the overall job design to parallel may result in a design where a synchronisation issue occurs.
This potentially make them unsuitable for conversion to a dataset, as Hashed Files support behaviours and usage patterns that datasets cannot replicate.
