Rick Kellogg updated STORM-18:
------------------------------
Component/s: storm-core
> Trident sections connected by a merge should not be required to enforce equal
> parallelisms
> ------------------------------------------------------------------------------------------
>
> Key: STORM-18
> URL: https://issues.apache.org/jira/browse/STORM-18
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Reporter: James Xu

> https://github.com/nathanmarz/storm/issues/322
> Currently, Trident enforces that partitionings are consistent, so that when
> Trident is forced to split up two pieces into separate bolts, an identity
> partitioning is used and the parallelism of the two parts must be identical.
> Enforcing this isn't necessary in a merge and in fact just makes it harder to
> have separate parallelisms for the different pieces.
> A current workaround is to manually set the partitioning to separate the
> pieces (like with a shuffle partitioning).
