Hey folks, I am going to start prototyping our media tier using cassandra as
a file system (meaning upload video/audio/images to web server save in
cassandra and then streaming them out)
Has anyone done this before?
I was thinking brisk's CassandraFS might be a fantastic implementation for
this
What is the best practices here to page and slice columns from a row.
So lets say I have 1,000,000 columns in a row
I read the row but want to have 1 thread read columns 0 - , second
thread (actor in my case) 1 - 1 ... and so on so i can have 100
workers processing 10,000 columns for
at the same time.

I hear that a bunch of folks have GeoIndexing built on top of Cassandra and
running in production.
Any of them open sourced (Twitter? SimpleGeo? Bueller?) planning on it?

If you are looking to store web logs and then do ad hoc queries you
might/should be using Hadoop (depending on how big your logs are)
While MongoDB has MapReduce (built in) it is there to simulate SQL GROUP BY
and not for large scale analytics by any means.
MongoDB uses a global read/write lock
I believe I have asked before but now that I am really getting into the
weeds with this it seems I am about to go down the MongoDB path... before I
do let me ask again (as I would prefer to stick with Cassandra for this app)

great talk tonight in NYC I attended in regards to using Cassandra as
a Lucene Index store (really great idea nicely implemented)

so Lucinda uses Cassandra as a distributed cache of indexes =8^)

it is kind of the classic distinction between OLTP OLAP.
Cassandra is to OLTP as HBase is to OLAP (for those SAT nutz).
Both are useful and valuable in their own right, agreed.
