Can you make this (and the similar instances) IntervalPredicate<Long> so my
compiler likes me again?
> Create a DSL-based timestamp lookup for profiler to enable sparse windows

> Key: METRON-690
> URL: https://issues.apache.org/jira/browse/METRON-690
> Project: Metron
> Issue Type: New Feature
> Reporter: Casey Stella
>
> I propose that we support the following features:
> * A starting point that is not current time
> * Sparse bins (i.e. the last hour for every tuesday for the last month)
> * The ability to skip events (e.g. weekends, holidays)
> This would result in a new function with the following arguments:
> from - The lookback starting point (default to now)
> fromUnits - The units for the lookback starting point
> to - The ending point for the lookback window (default to from + binSize)
> toUnits - The units for the lookback ending point
> including - A list of conditions which we would skip.
> weekend
> holiday
> sunday through saturday
> excluding - A list of conditions which we would skip.
> weekend
> holiday
> sunday through saturday
> binSize - The size of the lookback bin
> binUnits - The units of the lookback bin
> Given the number of arguments and their complexity and the fact that many,
> many are optional,
> PROFILE_LOOKBACK accept a string backed by a DSL to express these criteria
> Base Case: A lookback of 1 hour ago
> PROFILE_LOOKBACK( '1 hour bins from now')
> Example 1: The same time window every tuesday for the last month starting one
> hour ago
> Just to make this as clear as possible, if this is run at 3PM on Monday
> January 23rd, 2017, it would include the following bins:
> January 17th, 2PM - 3PM
> January 10th, 2PM - 3PM
> January 3rd, 2PM - 3PM
> December 27th, 2PM - 3PM
> PROFILE_LOOKBACK( '1 hour bins from 1 hour to 1 month including tuesdays')
> Example 2: The same time window every sunday for the last month starting one
> hour ago skipping holidays
> Just to make this as clear as possible, if this is run at 3PM on Monday
> January 22rd, 2017, it would include the following bins:
> January 16th, 2PM - 3PM
> January 9th, 2PM - 3PM
> January 2rd, 2PM - 3PM
> NOT December 25th
> PROFILE_LOOKBACK( '1 hour bins from 1 hour to 1 month including tuesdays
> excluding holidays')
