4. Data Grid
Red Hat Confidential

5. Distributed Cache
Fast access to data
Performance boost
Elasticity
High Availability
JSR 107 (Temporary Caching for the Java Platform)
– read, write, expiration, write-through, distribution
– JBoss Cache

7. Data Grid
Evolution of distributed caches
Well-known pattern to boost data access
performance and scalability
Clustered by nature
JSR 347 (Data Grids for the Java Platform)
– Querying, map-reducing standard way, consistency
– Infinispan

8. Infinispan
Red Hat Confidential

9. Infinispan
Distributed in-memory key/value data grid
and cache
Distributed as library and server
Highly available
Elastic
Manageable
Open Source

10. Architecture: Standalone Lib
Library Mode - standalone
Infinispan
App
JVM
JCP 107 Style Cache
– Just cache with advantages: expiry, j2ee transaction

11. Architecture: Clustered Lib
Use as library
Library Mode
Infinispan
– More feature
App
– Richer APIs
JVM
– Programmatic/decla
rative configuration
Infinispan
App
Cluster
– Extendable/embedd
able
JVM
Infinispan
JVM
App
– Faster (API call)
– App doesn’t know
it’s on cluster

12. Architecture: Server
Use as server
Server Mode
Infinispan
JVM
• Memcached, RE
ST, Hot
Rod, WebSocket
App
App
Infinispan
– Data tier shared
by multiple apps
Cluster
JVM
Infinispan
App
– Remote
JVM
– App doesn’t
affect cluster
– Non-java clients
• Java, C++,.NET,
Ruby, Python

13. Architecture: Durability

Cluster
persistence
– By replication
– By persistence
– By replication to
other cluster
(topology aware)

14. Clustering
Peer to Peer
– No central master, no single point of failure, no
single bottle neck
JGroups
– Reliable multicast communication library, nodes
discovery, sharing data, performing cluster scaling
Consistent Hash
– Hash based data distribution
– How it finds where data locates
Linear in nature: throughput, capacity

15. Cluster Mode: Replication

18. Monitoring/Management
MBeans on CacheManager, Cache
RHQ (JON, JBoss Operations Network)

19. Infinispan
Key Features
Red Hat Confidential

20. Key Features: Persistence
Used for durability
Cache Store – persistence storage
– File
System, Cloud, Remote, JDBC, JPA, LevelDB, Cassa
ndra, HBase, MongoDB, BerkeleyDB, JDBM, REST
Write-through, write-behind
Store chain
Shared store

21. Key Features: Transactions
JTA Transaction Support
Support MVCC (Multi-Versioned Concurrency
Control)
Isolation Level
– READ_COMMITTED (default)
– REPEATABLE_READ
Locking Mode
– Optimistic Lock (default)
– Pessimistic Lock

22. Key Features: Query
JBoss Hibernate Search + Apache Lucene
Query on values
Index Directory
– Lucene Directory: in-memory, file system, JDBC
– Infinispan Directory
Distributed Queries

23. Key Features: Map/Reduce
Based on Distributed Execution Framework
Mapper, Reducer, Collator, MapReduceTask

24. JDG, JBoss Data Grid
Red Hat JBoss Data
Grid
Infinispan-based
JON
All the benefits of
subscription, including
Red Hat world class
support and services

25. Use Cases
Red Hat Confidential

26. Infinispan on JBoss AS7
Used for WAS clustering, Hibernate L2 cache
Application gets cache with JNDI name
using @Resource

27. Session Clustering

28. Big Data Real-time
Processing
Infinispan Data Grid
