Thanks for the reply Aaron. I was thinking along the same lines as well.. as its only specific nodes that were showing excessive writes.. during the heavy read operations. We will be performing the same exercise again today.. where can I see within the JMX info if a specific node is performing a

Just to clarify, the data that we're loading SSTables from (v1.0.3) doesn't have compression enabled on any of the CF's. So in theory the compression should occur on the receiving end (v1.1.1) as we're going from uncompressed data to compressed data. So I'm not sure if the bug you mention is cau

Thanks Sylvain. I had a look at a node where we streamed data to and I do indeed see the "..-CompressionInfo.db" files.. However, prior to running the "upgradesstables" command, the total size of all the SSTables was 27GB and afterwards its 12GB. So even though the CompressionInfo files were the
