Ordered Processing

[vigith]

Summary

Numaflow improves throughput by pushing the next "work" to any available processing unit and thus inherently does out-of-order processing (similar to other stream processing platforms). However, there are a few cases where the "work" has to be ordered, e.g., the create-update-read-delete flow. You cannot update before you have created an item. Hence, it would be good to support some kind of partitioned FIFO where, within a partition, the work is ordered.

E.g., for a given partition A, N^th should be done only after (N-1)^th is done.

CAVEATs

• Auto-scaling

Use Cases

• create-update-read-delete workflows
