ASF GitHub Bot commented on METRON-1090:

Github user mattf-horton commented on the issue:

So a bunch more comments came in while I was writing the above. Nick's
comment about enrichments using assignment already of course modifies my
comment about Profilers, etc. Just making it uniform would give users a lot
less to wonder about.
As for := vs =, it's not so terrible to have both as exact synonyms. This
gives you both your preferred aesthetics and backward compatibility.
> STELLAR Add Assignment capability to Stellar language

> Key: METRON-1090
> URL: https://issues.apache.org/jira/browse/METRON-1090
> Project: Metron
> Issue Type: New Feature
> Reporter: Otto Fowler
> Assignee: Otto Fowler
> Priority: Major
>
> Add support for =, +=, -=, *=, /= for variables in stellar.
> foo = 5 returns 5 AND sets foo to 5 if the VariableResolver supports it.
> The shell should be changed to assign variables using this syntax, because
> exposing the left side to stellar allows catching errors for invalid keywords
> in left side.
