Carl Yeksigian commented on CASSANDRA-5042:
-------------------------------------------
I'm working on a new compaction strategy that would use a manifest. It will
have a fixed set of levels rather than dependent on the sstable size, so we
need a new class to represent the manifest. Making a class that both
implementations subclass makes more sense than subclassing leveledmanifest.

> Reporter: Carl Yeksigian
> Priority: Minor

> The idea of the compaction manifest seems like a general one for different
> compaction strategies.
> In a few places, leveled manifest is named directly, e.g. Directories. Those
> places should be changed to just refer to manifest. Also, leveled manifest
> should be broken out into an abstract class which contains the generations
> without knowledge of what the different generations are. This way, leveled
> manifest remains for leveled compaction, while other compaction strategies
> can use the abstract manifest.
