Subject Using Cassandra as an object store
Date Fri, 19 Apr 2019 05:25:16 GMT

I'm looking at the possibility of using cassandra as an object store to
offload image/blob data from an Oracle database.  I've seen mentions of it
being used as an object store in a large scale fashion, like with Walmart:

However I have found little on small scale setups and if it's even worth
using Cassandra in place of something else that's meant to be used for
object storage, like Ceph.

Additionally, I've read that cassandra struggles with storing objects 10MB
or larger and it's recommended to break objects up into smaller chunks,
which either requires some kind of middleware between our application and
cassandra, or it would require our application to split objects into
smaller chunks and recombine them as needed.

I've looked into pithos and astyanax, but those are both no longer
developed and I'm not seeing anything that might replace them in the long
term.

Any helpful information or advice would be greatly appreciated.

Thanks in advance.
