T Jake Luciani commented on CASSANDRA-1472:
-------------------------------------------
I'm definitely not wanting to boil the ocean here. We could take the easy
approach but at the cost of supporting something we know will soon change.
Perhaps this should all go into another set of tickets that we make blockers to
this issue.
Overall I am thinking about our current file format issues and what we know we
need: checksums + compression. The lucene and compression code I mentioned is
quite straight forward so I think it would be pretty easy to get something
working here, and it would serve as a basis for our new sstable format whatever
that ends up being or simply adding these features to our current format.
The main blocker of this ticket is the avro dependency so just trying to get
enough functionality to support the most basics of a disk format here.

> Bitmap indexes are a very efficient structure for dealing with immutable
> data. We can take advantage of the fact that SSTables are immutable by
> attaching them directly to SSTables as a new component (supported by
> CASSANDRA-1471).
