Company will add clustering to open source database MySQL plans to integrate high-availability clustering technology into its open source database through the acquisition of Alzato, announced on Tuesday.Alzato, a venture company started by Ericsson in 2000, has developed and marketed NDB Cluster, a high-availability data management system designed for telecom/IP environments, according to MySQL. The technology will provide a high-availability clustering data management engine for systems that require maximum uptime and real-time performance, such as in telecom, network applications, and heavy-load Web sites, MySQL said. Alzato’s technology will be offered in a version of the MySQL database planned for release in 2004 and tentatively called MySQL Cluster.Alzato technology expands existing high-availability capabilities in the MySQL database and also provides for fast recovery, said Marten Mickos, CEO at MySQL. “We can offer high-availability at a totally new scale,” he said.MySQL customers in areas such as network equipment manufacturing and telecom have growing demands for high-availability functionality, Mickos said. The company would not reveal the cost of the Alzato acquisition, which actually closed a month ago. DatabasesSoftware DevelopmentTechnology IndustrySmall and Medium Business
