Daniel Halperin commented on BEAM-344: -------------------------------------- [~tgroh] Some of this is now happening. How much? Starter bug (if not complete)? > Merge, Split, Delay, and Reorder bundles in the DirectRunner > ------------------------------------------------------------ > > Key: BEAM-344 > URL: https://issues.apache.org/jira/browse/BEAM-344 > Project: Beam > Issue Type: Improvement > Components: runner-direct > Reporter: Thomas Groh > Priority: Minor > > PCollections have no guarantees about the ordering of elements between steps > Randomly reordering, splitting and merging bundles will break user pipelines > which assume some order will be maintained between steps and within a bundle. > This assumption is not correct, so should break in the Direct Runner. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
