8. TURKCELL DAHİLİ Oracle Coherence is the industry leading in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data Basics of Coherence

9. TURKCELL DAHİLİ Types of Usage Data Transfer Active-Passive Process of multiple applications Storage-Enrichment Assurance of dataflow Coherence Usage in RBM

10. TURKCELL DAHİLİ Data Transfer Each application has a CQC(Continuous Query Cache) Each application has an input queue(Blocking Queue) Each application redirects/deletes Cache Item Coherence Usage in RBM

11. TURKCELL DAHİLİ Coherence Usage in RBM Data Transfer Application reads items from DB Each application adds its identity into «Application Registry» cache Application sets their «next dest» area by Round Robin(load balancing) and inserts into the cache

13. TURKCELL DAHİLİ Coherence Usage in RBM Active-Passive Process of multiple applications

14. TURKCELL DAHİLİ Coherence Usage in RBM Storage-Enrichment Storage cache, we use, are for preventing unnecessary outer systemcalls

15. TURKCELL DAHİLİ Coherence Usage in RBM Storage-Enrichment Enrichment cache includes 35M items which are consist of outer system data(54 GB memory usage in 9 nodes over 3 machines) In order to prevent unnecessary system calls, events are enriched with outer system data

16. TURKCELL DAHİLİ Coherence Usage in RBM Assurance of Data Flow In order to prevent data loss and functually operate replays/retrys of data, events are being stored temporarily Each application is responsible to remove the item which is being processed by itself A filter operates over cache periodicly to get the items which have not been processed Result of the filter, items which have not been processed yet, are sent into the process again

17. TURKCELL DAHİLİ Conclusion RBM is a very important project for Turkcell The expectation from RBM is getting higher each day Coherence Cache has a major role in this state of RBM We used Coherence in a lot of place of the project for different purposes In order to increase performance, more usage of Coherence will be needed in the future
