[xwiki-devs] [Video] XWiki-G3 demo - XWiki cluster storing native Java objects in Cassandra distributed store.
Hi, Over in the XWiki Research Department, we've been working on some exciting new developments. While XWiki provides industry leading flexibility for defining, storing and querying data structures in SQL based stores, we are researching how to bring storage to Cassandra distributed NoSQL data store and give you the power to define and store your own true Java native Objects. In this demonstration we run 2 integrated XWiki/Cassandra nodes and show changes propagating from one to the other as we edit pages. We show that you can stop one node and the wiki is still fully functional with only one node running. Then we restart the downed node and show the edits which were made while the node was down propagating over from the running node. XWiki documents and objects are stored in an integrated Cassandra NoSQL Cloud data store allowing for horizontal scalability without any single point of failure. Users can define XClasses using the XWiki class creation interface and those XClasses are compiled into native Java classes which can be loaded and stored in the Cassandra distributed store. Here is the demonstration video: https://www.youtube.com/watch?v=NngAKdeWuH0 While this is still in heavy development, we hope to be bringing up live nodes for you to play with as soon as possible. Thanks, Caleb
Oops, sent that one twice. Sorry about the noise. Caleb On 07/03/2012 07:39 PM, Caleb James DeLisle wrote:
