Chandni Singh commented on APEXMALHAR-2065:
-------------------------------------------
In FSWindowDataManager we are already keeping track of all the window Ids for
which data is available per operator partition. Tim's change only makes this
data available.
The way I am approaching changing the WindowDataManager to use WAL is keeping
all the api and functionality consistent and just changing the implementation
so right now I can't see any issues with WAL version.

> This method will return all the windows id's across all partitions for which
> there is data.
> This method is required for dynamic repartitioning of Managed State because
> the data for all the partitions must be loaded.
