>             Project: Phoenix
>          Issue Type: Improvement
>    Affects Versions: 5.2.0
>            Reporter: Viraj Jasani
>            Assignee: Viraj Jasani
>            Priority: Major
>             Fix For: 5.2.0
>
>
> Some improvements/fixes for Phoenix Table MaxLookback and TTL feature:
>  * Use overridden value of maxLookback ms while confirming whether region 
> level compaction is required
>  * Use map of table with map of ColumnFamily to MaxLookback value for the 
> override API
>  * For the entire row version that is within max lookback window, avoid extra 
> region level compaction
>  * Support DeleteFamilyVersion marker with DeleteFamily markers such that 
> DeleteFamilyVersion marker can mask only Put cells with the same timestamp. 
> This requires changes to how we build and consume the column list for all 
> cells that are outside the maxLookback window. The changes are required in 
> both phoenix and hbase level compaction. We need to retain 
> DeleteFamilyVersion markers as they can be used to perform masking of old 
> cells (inside or outside of TTL window). The combination of DeleteFamily and 
> DeleteFamilyVersion markers need more tests.
