Progress Apama Gets Failover Features


By Alex Handy
December 15, 2006 — 
The new version of Progress Software’s Apama seeks to add stability to this complex event processing software with failover capabilities that can push out a clogged process and replace it with a fresh version, unfettered by slowdowns.

Mark Palmer, vice president of event stream processing for Progress Apama, said that the new failover features of the Apama platform can reduce downtime and the possibility of overall system failure, essential requirements for the high-speed algorithmic trading companies Apama targets. The secret to this new feature is in the event stream processor, or corellator, as Palmer calls it.

“With 3.0 they can have these corellator instances doing their trading; then if anything happens, it’ll fail over,” said Palmer. That means a jammed corellator will be jettisoned in favor of a new one loaded with the state information left over by the failed instance.

Progress Apama 3.0 also adds a new event stream interaction API. This interface gives developers a new programmatic way to create and modify process rules. Progress has also added an Eclipse-based rules development environment for business analysts who don’t want to rely on IT to build their trading algorithms.
