What is Terracottas involvement with Quartz?
Terracotta acquired the rights to the Quartz Scheduler project in November, 2009. Terracotta and the original Quartz team together can provide improved features and services for Quartz. Quartz is still (and always will be) an open source project with contributors from around the world. Terracotta brings additional expertise for improving some of the advanced features of Quartz, and offers commercial support services to Quartz users.
