Presentation delivered by Mircea Markus (JBoss) at the London JBoss User Group Event on Wednesday, the 4th of December 2013. In this talk, Mircea Markus (Infinispan Lead) covers the major features added in the 6.0 release to the Infinispan ecosystem: - querying in client/server mode - better integration with the persistent storage - multi-master cross-site replication - support for heterogeneous clusters Participants will take home a better understanding of Infinispan capabilities and the use cases in which it can be put at work. Ideally the attendees should have a basic knowledge of the in-memory data grids.

7. Cpp Hot Rod client
•Hot Rod
•Binary protocol
•3 levels of intelligence
•Clients in Java(L3), Python(L1), Ruby (L1)
•Cpp client
•L3
•RHEL5, RHEL6, Windows 7
•OSS/Apache licence

8. Querying - existing
•Embedded mode only
•Based on Hibernate Search/Lucene
•Objects in the grid are indexed
•index management

9. Remote Querying
•Language neutral
•client/server access : Hot Rot
•type representation : protobuf & protostream
•DSL for querying
•Schema management
•protofiles
•JMX

10. Define schema - protobuf

11. Serialize to protobuf
•Protobuf tooling
•schema to cpp/java. Not the other way around
•constraining on the format of your domain
•Protostream
•protobuf serializer developed by Red Hat
•OSS/Apache licensed
•flexible
•strongly typed

12. Implement marshallers based on schema

13. Implement marshallers

14. Execute the query

15. Langauge neutral access
•“Side effect”
•HotRod
•interoperabilut

16. Further query improvements
•Query on non-indexed fields
•HotRod Cpp client
•query DSL
•protostream
•protobuf default serialization (?)
•better schema management

17. New Persistence SPI
•Simpler
•no locking
•no transaction
•Faster
•parallel iteration/expiry
•reduced serialization overhead
•Aligned with JSR-107
•easier migration

18. New Local (File) Store
•Very popular
•easy setup/no dependencies
•New file store
•fast!
•keeps all keys in memory
•courtesy @Karsten Blees

19. X-Site replication
•Since Infinispan 5.2.0
•Hot-standby for geographic failover
•Follow the sun

20. Cross Site Replication

21. Multiple site masters
•Single site master (5.2.x)
•does not scale
•mitigated by capacity-factor (6.0.0)
•Multiple site masters
•site masters form a jgroups cluster
•configurable number

22. Heterogenous clusters
•Heterogenous clusters
•not all machine are equally powerful
• some are more busy
•Load-factor
•e.g. 0.5 -> half of the average load
•0 is acceptable
•alternative to client/server

23. New Licensing
•LGPL -> Apache License
•Apache License
•open source
•considered more business friendly
•better integration with other Apache licensed projects

24. Roadmap
•Eventing over Hot Rod
•Clustered listeners
•Security
•Query over Cpp Hot Rod
•Better partition handling
•C# Hot Rod client
