Yuki Morishita commented on CASSANDRA-10990:
--------------------------------------------

One more suggestion.
Isn't it simpler to just have CachedInputStream that first fills on heap buffer 
and writes out to file as buffer gets full?

bq. Do you easily remember if there is a way to retrieve the average partition 
size for a given table? I remember seeing something along those lines but I'm 
not sure where it is.

I think we can just set to be more sane value (few hundreds kilobytes?), the 
use case here is for static columns only.

> In 2.0 we introduced support for streaming older versioned sstables 
> (CASSANDRA-5772).  In 3.0, because of the rewrite of the storage layer, this 
> became no longer supported.  So currently, while 3.0 can read sstables in the 
> 2.1/2.2 format, it cannot stream the older versioned sstables.  We should do 
> some work to make this still possible to be consistent with what 
> CASSANDRA-5772 provided.
