Re: CQLSSTableWriter memory leak

We figured out the reason for the growing memory usage. When adding rows, if flush-to-disk operation is done in SStableSimpleUnsortedWriter.newRow(). But for the compound primary key case, when the clustering key is identical, there is no new row created. So the single huge row is kept in the

Re: ANNOUNCEMENT: cassandra-aws project

I guess I didn't know about the ComboAMI! Thanks! I'll look into this. I have been rolling my own AMIs for a simple reason -- we have on-premises environments and in AWS. I wanted them to be the same, structurally, so I used our on-prem configurations as a starting point. Regards, Oleg On

python fast table copy/transform (subject updated)

Hi Marcelo, I have updated the prerelease app in this gist: https://gist.github.com/michaelplaing/37d89c8f5f09ae779e47 I found that it was too easy to overrun my Cassandra clusters so I added a throttle arg which by default is 1000 rows per second. Fixed a few bugs too, reworked the args, etc.

Re: VPC AWS

This may not help you with the migration, but it may with maintenance management. I just put up a blog post on managing VPC security groups with a tool I open sourced at my previous company. If you're going to have different VPCs (staging / prod), it might help with managing security groups.

Data model for streaming a large table in real time.

We have the requirement to have clients read from our tables while they're being written. Basically, any write that we make to cassandra needs to be sent out over the Internet to our customers. We also need them to resume so if they go offline, they can just pick up where they left off. They
