Dave Brosius edited comment on CASSANDRA-5555 at 5/24/13 3:50 AM:
------------------------------------------------------------------
A premature patch added to see if approach is relatively ok, haven't formulated
tests yet, so *definitely* not ready yet.
Also note that this implementation leaks into StorageService, which is probably
not desired, and a real fix probably wants a separate interface into
SSTableLoader.stream() as opposed to a complete replace. But not sure.

> With the default heap size, sstableloader will OOM when there are roughly 25k
> files in the directory to load. It's easy to reach this number of files in a
> single LCS column family.
> By avoiding creating all SSTableReaders up front in SSTableLoader, we should
> be able to increase the number of files that sstableloader can handle
> considerably.
