> Project: Apache Lens
> Issue Type: New Feature
> Components: cube
> Reporter: Sharad Agarwal
> Assignee: Sharad Agarwal

> Fix For: 2.3

> Attachments: lens-251.1.patch
>
>
> For certain stores that allows streaming ingestion, to make the data
> available immediately for querying, we need the notion of streaming update
> period or some such.
> Describing by example:
> - lets say there are two drivers - D1 and D2.
> - D1 queries storage S1
> - D2 queries storage S2
> S1 and S2 are part of the same Cube.
> In S1 data is in hourly granularity loaded every hour, while S2 has data
> being ingested continuously in streaming fashion and maintains last 5 hours
> window of data.
> Now based on the query time range we want to select the right driver.
