servers for cassandra
Hi I am just curious to know if there is any hosting company that provides servers at a very low cost, wherein I can install cassandra on WAN. I have cassandra setup in my LAN and want to test it in real conditions, taking dedicated servers just for testing purposes is not at all feasible for me not even pay-as-you go types. I'd really appreciate if anybody can share information on such hosting providers.

Re: servers for cassandra
As of now I think only rackspace.com support cassandra in der cloud webhosting which will cost around $150 to $200 a month. Der is no cheap kinda thing in cassandra because data is distributed in multiple servers. I advice you to test on ur LAN only. You can do benchmark testing to test real conditions. I use 64 bit linux (ubuntu) with 4GB RAM that is more than sufficient to play around. ___ *Samal Gora**i* On Sat, Sep 4, 2010 at 12:05 PM, vineet daniel vineetdan...@gmail.comwrote: Hi I am just curious to know if there is any hosting company that provides servers at a very low cost, wherein I can install cassandra on WAN.

Re: servers for cassandra
you can get a vps and configure it to run cassandra. i guess it will be cheaper. max 40$ /month On Sat, Sep 4, 2010 at 4:42 PM, samal gorai samalgo...@gmail.com wrote: As of now I think only rackspace.com support cassandra in der cloud webhosting which will cost around $150 to $200 a month.

Re: 4k keyspaces... Maybe we're doing it wrong?
Yes, right now it's probably not technically possible, from a resource point of view, to run 4k keyspaces in a cassandra cluster. Those management features you may have been able to do as meta data operations will prob become long running background tasks.

Thank you So it sounds like other than being able to quickly truncate customer-keyspaces, with Cassandra there's no real benefit in keeping each customer data in a separate keyspace. We'll suffer on the memory side with all the switching between keyspaces and we're better off storing all customer data under the same keyspace?

The is more support for multi tenancy systems but a lot of the memory configuration is per keyspace/column family, so you cannot run that many keyspaces.

All database schemas are identical. With MySQL, we used to provision a separate 'database' per each client, to make it easier to shard and move things around. Does it make sense to migrate the 4,000 MySQL databases to 4,000 keyspaces in Cassandra? Or should we stick with a single keyspace? My concerns are - #1. Will every single node end up with 4k folders under /cassandra/data/? #2. Performance: Will Cassandra work better with a single keyspace + lots of keys, or thousands of keyspaces? - Granted it's 'cleaner' to have a separate keyspace per each client, but maybe that's not the best approach with Cassandra. Thoughts?
