Storing large blobs
Has anyone had experience storing large blobs in Cassandra? Is really Cassandra tailored for large content?

It's not tailored for it, but it works "well enough" for some
applications. Better than having to deal with two different data
stores.

When just starting to use Cassandra I had serious issues with 0.5 and
blobs (compressed JSON) over 500 MB, but it was because of the heap size
and not something inherently broken in Cassandra.

It is practically a seek and large streaming read. I do not believe this
would be an issue. I have never run such a workload but a simple experiment
should clear the air.

We could have blob as large as 50mb compressed (XML compresses quite well). Typical documents we would deal with would be between 500K and 3MB

My question would be how large is large? Perhaps you could compress the blobs and then store them. But it depends on the answer to the first question.
