Jonathan Ellis commented on CASSANDRA-946:
------------------------------------------
Can you do the load with (paging) getRangeSlice calls? That's going to be much
better than a row load for each sstable key (which will have duplicates),
especially when CASSANDRA-821 is done.
> Add a configuration and implementation to populate the data into memory

> Proactively load data into the memory when the node is started, there will be
> a configuration to enable this function and will be per Columnfamily. The
> requirement is to speed up the reads for data which can reside 100% of in the
> memory.... In addition to enabling the RowCache to 100% we can do this so as
> upgrades or any other means of restart will not clear the cache in the server.
