> Key: METRON-575
> URL: https://issues.apache.org/jira/browse/METRON-575
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.3.0
> Reporter: Nick Allen
> Assignee: Nick Allen
> Fix For: 0.3.1
>
>
> The ProfileBuilderBolt incorrectly assumes that it will only ever see a
> single [profile, entity] pair. The bolt maintains a single StellarExecutor
> that is responsible for executing the init, update, result expressions. This
> assumption is incorrect as Storm's field grouping only guarantees that the
> same profile/entity pairs will go to the same task. Storm does not guarantee
> that a task only receives a single profile/entity pair.
> The easiest fix is to maintain a cache that maps a profile/entity to its
> state. This would follow what is currently done in the Join bolt.
