Re: How many BATCH inserts in to many?

[Radim Kolar]

do not use cassandra for implementing queueing system with high 
throughput. It does not scale because of tombstone management. Use 
hornetQ, its amazingly fast broker but it has quite slow persistence if 
you want to create queues significantly larger then your memory and use 
selectors for searching for specific messages in them.

My point is for implementing queue message broker is what you want.
