Benedict commented on CASSANDRA-7443:
-------------------------------------

First impression is pretty positive - this is looking a lot cleaner than I 
might have hoped.

A few initial comments, obviously bearing in mind it's still in progress:

* I'm not super keen on using Class.getConstructor() for instantiating a 
reader/writer. Would prefer a factory method / class; using reflection for long 
type parameter lists worries me.
* Would prefer DatabaseDescriptor.getDefaultSSTableFormat, and permit overrides 
per Table
* LazilyCompactedRow is still tightly coupled with Big format (relates to 
AbstractCompactedRow as you mentioned)
* Streaming _may_ need a bit more work/thought - seems that compression format 
of sstables is coupled quite tightly with compression stream writer, and also 
assumes we can stream a single file range. Might not want to impose that 
requirement (we probably don't for 3.0 format - a set of ranges is more likely, 
but I would prefer to abstract the concept of a stream Chunk to be format 
specific anyway, to remove the coupling)

> As part of a wider effort to improve the performance of our storage engine we 
> will need to support basic pluggability of the SSTable reader/writer. We 
> primarily need this to support the current SSTable format and new SSTable 
> format in the same version.  This will also let us encapsulate the changes in 
> a single layer vs forcing the whole engine to change at once.
> We previously discussed how to accomplish this in CASSANDRA-3067
