T Jake Luciani commented on CASSANDRA-1278:
-------------------------------------------
I understand why you did what you did here, but the concept of taking thrift
encoded data over gossip then creating into thrift objects to create row
mutations feels, well, bulky :)
It seems like there would be a way to refine what you've done to go from client
-> memtable more quickly.
if you took the column and supercolumn serializers and streamed the delimited
byte arrays you would build up a CSLM<ByteBuffer,ByteBuffer> and call
SSTableWriter.append once it's "full"
You could then kick off secondary index rebuilding in the background.

> Currently bulk loading into Cassandra is a black art. People are either
> directed to just do it responsibly with thrift or a higher level client, or
> they have to explore the contrib/bmt example -
> http://wiki.apache.org/cassandra/BinaryMemtable That contrib module requires
> delving into the code to find out how it works and then applying it to the
> given problem. Using either method, the user also needs to keep in mind that
> overloading the cluster is possible - which will hopefully be addressed in
> CASSANDRA-685
> This improvement would be to create a contrib module or set of documents
> dealing with bulk loading. Perhaps it could include code in the Core to make
> it more pluggable for external clients of different types.
> It is just that this is something that many that are new to Cassandra need to
> do - bulk load their data into Cassandra.
