---------------------------------
Summary: State from different profiles can be co-mingled
incorrectly
Key: METRON-575
URL: https://issues.apache.org/jira/browse/METRON-575
Project: Metron
Issue Type: Bug
Reporter: Nick Allen
Assignee: Nick Allen
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.
