> Currently rocksdb compactions are tracked for getting the intermediate
> SstFiles and forming a complex DAG. Instead of tracking the compactions
> simple SstFlushes can be tracked to get all the L0 sstFiles b/w 2 snapshots
> which could be just implemented as a simple linked list of sst files. We can
> even compact the sst files between 2 consecutive snapshots which would make
> the snapshot diff even more optimized and also simplify the design.
