> Decouple Timestamp calculation from PROFILE_GET
> -----------------------------------------------
>
> Key: METRON-684
> URL: https://issues.apache.org/jira/browse/METRON-684
> Project: Metron
> Issue Type: Improvement
> Reporter: Casey Stella
> Assignee: Casey Stella
>
> Currently PROFILE_GET only supports a static lookback of a fixed duration.
> As we have more complicated, potentially sparse, lookbacks (e.g. the same
> time slice every tuesday for a month), it would be nice to decouple the
> construction of timestamps from PROFILE_GET into its own set of functions.
