Re: Using cassandra a BLOB store / web cache.

Just adding one more item to the discussion. I believe this was announced on the list some time ago. I haven't tried it out yet, just pointing it out since it's on the OP's topic: http://pithos.io/ It's a Cassandra-backed object store using an S3 API. On Tue, Jan 19, 2016 at 2:07 PM, Richard L.

I would ask why do this over say HDFS, S3, etc. seems like this problem has been solved with other solutions that are specifically designed for blob storage? On Tue, Jan 19, 2016 at 4:23 PM, wrote: > I recently started noodling with this concept and built a working blob > storage service using n

Re: Using cassandra a BLOB store / web cache.

I recently started noodling with this concept and built a working blob storage service using node.js and C*. I setup a basic web server using the express web server where you could POST binary files to the server where they would get chunked and assigned to a user and bucket, in the spirit of S

Re: Using cassandra a BLOB store / web cache.

Lots of interesting feedback.. I like the ideal of chunking the IO into pages.. it would require more thinking but I could even do cassandra async IO and async HTTP to serve the data and then use HTTP chunks for each range. On Tue, Jan 19, 2016 at 10:47 AM, Robert Coli wrote: > On Mon, Jan 18, 2

Possible to adjust tokens on a vnode cluster?

I have a 24 node cluster, with vnodes set to 256. 'nodetool status ' looks like this for our keyspace: UN 588.23 GB 256 11.0% 0c8708a7-b962-4fc9-996c-617da642d9ee 1a UN 601.33 GB 256 11.3% 5ef60730-0b01-4a8b-a578-d828cdf78a1f 1b UN 613.02 GB

I ran through those issues a while ago. It was on Ubuntu rather than OSX but probably the same. I compiled my steps here: http://mrcalonso.com/fitting-ipython-notebooks-spark-and-cassandra-all-together/ Cheers! Carlos Alonso | Software Engineer | @calonso On 19 Ja
