>
> 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.
