Hi Maxim, If you need to store Blobs, then BlobStores such as OpenStack Object Store (aka Swift) should be better choise. As far as I know, MogileFS (which is also a sort of BlobStore) has scalability bottleneck - MySQL. There are few reasons why BlobStores are better choise. In the follow

Chunking is a good idea, but you'll have to do it yourself. A few of the columns in our application got quite large (maybe ~150MB) and the failure mode was RPC timeout exceptions. Nodes couldn't always move that much data across our data center interconnect in the default 10 seconds. With enough he

Hello everybody, I'm being asked whether we can serve an "object", which I assume is a blob, of 750MB size? I guess the real question is of how to chunk it and/or even it's possible to chunk it. Thanks! Maxim
