@cestella I think we want at least one more to capture making this
available in the management UI (I'd argue that should inform any REST API task,
so I'm not sure if we want that also created as a ticket).
> Parser aggregation in storm
> ---------------------------
>
> Key: METRON-1657
> URL: https://issues.apache.org/jira/browse/METRON-1657
> Project: Metron
> Issue Type: Bug
> Reporter: Justin Leet
> Assignee: Justin Leet
> Priority: Major
>
> Currently our parsing solution requires one storm topology per sensor. It has
> been complained that this may be wasteful of resources and that, rather than
> one storm topology per sensor, it would be advantageous to have multiple
> sensors in the same topology. The benefit to this is that it would require
> fewer storm slots.
> The issue with this is that whenever we've aggregated functionality like this
> before, we've run into issues appropriately being able to scale storm (e.g.
> batch vs random access indexing in the same topology). The main point in
> addressing this is to recommend that parsers with similar velocities and
> complexity are grouped together.
> Particularly for a first cut, leave the configuration mostly as-is, while
> allowing for comma separated lists of sensors in start_parser_topology.sh
> (e.g. bro,yaf creates a aggregated parser consisting of those two).
