It also has a free version called NCache Express. Although this product is in .net domain but it works well with java too. hi,

You can get more details on the licensing here: http://www.terracotta.org/web/display/docs/FAQ#FAQ-LicensingFacts But in essence, unless you are redistributing Terracotta - e.g. you make an application that relies on Terracotta, you bundle that application up and then sell it, you are now redistributing. @Rik,

You can achieve the effect of partitioning by appropriate request routing to cluster nodes so that the necessary object will always be found on that local server and therefore synchronization overhead between terracotta server and cluster nodes minimized.

It is expensive to route http requests within a user's session to any node of a cluster? Thanks --Mahesh Hi,

If yes, where? Its not feasible to include it in each SMS, given the limited capacity of an SMS. Hi Taylor,

would applications that use SMS to communicate with endusers need to provide attribution? If yes, where? Its not feasible to include it in each SMS, given the limited capacity of an SMS.

Really great write-up. Wow! One minor correction, the Terracotta license requires attribution (adding "Powered by Terracotta") only for users that are re-distributing. Normal uses of Terracotta would not require this restriction. More info is available on our licensing page: http://www.terracotta.org/web/display/orgsite/Licensing Once again, impressive summary of all of our available information. Regards, Taylor Gautier Product Manager, Terracotta Hi Piotr.
