1 like1,560 views
Infinispan 6.0 introduces various enhancements, including a new C++ Hot Rod client, improved querying in client/server modes, and integration for persistence. Key features also include cross-site replication improvements, support for heterogeneous clusters, and a shift from LGPL to a more business-friendly Apache license. The documentation outlines the roadmap for future advancements like eventing over Hot Rod and enhanced security measures.

- 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
- 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
- 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
