Frequently Updated Wide Rows - Suggestions

Hello Everybody,

In my use case we use Wide Rows whose columns are frequently updated,
deleted and created.

I was wondering if this case fits the Cassandra pattern and if there are
any precautions to be taken.

Kindly advice!

That scenario can result in slower reads than narrow rows that are updated less frequently. 

Like most things it depends. Do you have a feel for how wide and what the update pattern is like ? 

Things like levelled compaction (http://www.datastax.com/dev/blog/leveled-compaction-in-apache-cassandra) can help. It's also pretty easy to run up a proof of concept to see what the read performance is like. 

Hope that helps.
