So what is the size limit for voltdb ..? From: Charles Woerner / IMAP [mailto:[email protected]] Sent: Wednesday, June 09, 2010 5:55 PM To: [email protected] Subject: Re: http://voltdb.com/ ?
Totally agree that Cassandra and voltdb fulfill different needs. I would say mysql cluster (ndbd) would be a more appropriate competitor. 50tb? Yes and no - it's designed to integrate with a system called vertica which does scale to that size, but as a stand alone system I don't believe so. -- Thanks, Charles Woerner On Jun 9, 2010, at 2:35 PM, Ned Wolpert <[email protected]<mailto:[email protected]>> wrote: As far as finding its competitors go; If you need acid compliance, Cassandra isn't in the list. If you need 50TB of data, is VoltDB in the list? On Wed, Jun 9, 2010 at 2:30 PM, Charles Woerner / IMAP <[email protected]<mailto:[email protected]>> wrote: I would disagree with that assessment. My take is that Voltdb is a high throughput, fault tolerant transaction processing db as opposed to a caching system or key value store. It's easy to get hung up on the in-memory nature of it but I believe that it is both fault tolerant through redundant copies of the data and fully acid compliant. -- Thanks, Charles Woerner On Jun 9, 2010, at 12:09 PM, AJ Slater <[email protected]<mailto:[email protected]>> wrote: Its proper competitors are stuff like redis and memcached.

After following up, I found out it requires the entire DB to reside in memory across the nodes.
