After all, if it were possible to lose the garbage-collection latency, wouldn't Sun have done it already? After testing WLRT 1.1 in several scenarios, we concluded BEA's solution works.”. - Network Computing, September 2006

11. What´s inside • Low Latency Deterministic Container • Lightweight “Application Server” • Event Driven Programming Model • Complex Event Processor (CEP) • Deployment Environment • Time and Event Driven Computing Summary

12. Low Latency Deterministic Container WLRT Deterministic GC • Provides QoS guarantees • Usage: ”-Xgcprio:deterministic –Xpausetarget=10ms • Highly tuned mostly concurrent mark-n-sweep GC • Most work done concurrently, pauses are frequent but very short • Back off, split work and reschedule if nearing QoS limit (divide and conquer) One GC cycle (phases 0-2, 2-4, 4-5, 5 visible) 500 ms 20 s

13. Lightweight “Application Server” • Built on the BEA “Core Engine” • Equinox OSGi Platform underneath • Mix of hardened WLS subsystems and new technologies (Spring-OSGi, Complex Event Processor, etc.) • Tuned I/O model • Refinements to WLS network I/O model • Blocking network I/O • One dedicated thread/connection • Tuned Threading model • Minimal (zero) thread switching • Can parallelize Rules execution or switch thread (if desired)

14. Event Driven Programming Model • Applications model complex event processing networks • Network of collaborating producers and consumers of events • Network nodes (stages) are: • Services: Adapter, Stream, Processor • Business Object: POJO (Spring Beans) • Events: POJO or Map • Spring-based declarative assembly and configuration • Applications configured in Spring configuration file • Custom Spring tags for WLEvS services • Dependency injection for additional services • Seamless integration to legacy Spring beans

15. Adapter User Code Processor Stream Event Driven Programming Model Data Source Stream Data Source Adapter Stream

16. Complex Event Processor (CEP) • Continuous query engine • Processes high volumes of streaming data • Filtering, Correlation, Causality, Aggregation • Evaluates in “Real-Time” (Sub-millisecond with high workloads) • SQL-based Event Processing Language (EPL) • Extensions to handle streaming Events • Runtime representation • Rules : compiled into Java code by Query Parser • Actions (user code): POJOs (Spring Beans) • Events: POJOs

17. Event Processing Language (EPL) • SQL-based • Leverage existing skill-sets • Easier integration to relational data • SELECT … FROM RETAIN … WHERE … GROUP BY … HAVING … MATCHING … OUTPUT … • Extensions to handle streaming data • WHEN ... THEN vs. IF ... THEN • Streaming Windows (sliding, jumping) • Time-based queries
