Your use-case is different than what i though. So basically you have only
one data source (the feed) and many consumers (the workers)
Only one worker is allowed to consumer the feed at a time.
This can be modeled very easily using distributed lock with C.A.S
*CREATE TABLE feed_lock (*

Sorry + thanks.
Unfortunately, I do not want to use C* as a queue, but to coordinate workers

@Jan
This subject of distributed workers & queues has been discussed in the
mailing list many times. Basically one implementation can be:
1) *p* data providers, *c* data consumers
2) create partitions (physical rows) of arbitrary number of columns (let's
say 10 000, not too big though). Partitio
Oh ok. I thought you did not have a cassandra cluster already. Sorry about
that.

Hey, I have got a C* cluster that can (poten
Though cassandra can work but to me it looks like you could use a
persistent queue for example (rabbitMQ) to implement this. All your workers
can subscribe to a queue.
In fact, why not just MySQL?

Hi,
maybe someone knows a nice solution to the following problem:
I have N worker processes that are intentionally masterless and do not know
about each other - they are stateless and independent instances of a given
service system.
These workers need to poll an event feed, say about every 10
