Data Grid
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

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

Infinispan
Infinispan
Distributed in-memory key/value data grid and cache
Distributed as library and server
Highly available
Elastic
Manageable
Open Source
Architecture: Standalone Lib
JCP 107 Style Cache– Just cache with advantages: expiry, j2ee transaction
Library Mode - standalone
Infinispan
JVM
App
Architecture: Clustered Lib
Use as library– More feature
– Richer APIs
– Programmatic/declarative configu-ration
– Extendable/embed-dable
– Faster (API call)
– App doesn’t know it’s on cluster

Architecture: Server
Use as server– Remote
• Memcached, REST, Hot Rod, WebSocket
– Data tier shared by multiple apps
– App doesn’t af-fect cluster
– Non-java clients• Java, C++,.NET,
Ruby, Python

Architecture: Durability
Durability– By replication
– By persistence
– By replication to other cluster (topology aware)

Clustering
Peer to Peer– No central master, no single point of failure, no sin-
gle 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
Cluster Mode: Replication

Cache onServer 1 K,V
Cache onServer 2 K,V
Cache onServer 4 K,V
Cache onServer 3 K,V
cache.put(K,V)
Cluster Mode: Distribution
Distribution Mode(numOwners=2)
Cache onServer 1 K,V

InfinispanKey Features
Key Features: Persistence
Used for durability
Cache Store – persistence storage– File System, Cloud, Remote, JDBC, JPA, LevelDB,
Cassandra, HBase, MongoDB, BerkeleyDB, JDBM, REST
Write-through, write-behind
Store chain
Shared store
Key Features: Transactions
JTA Transaction Support
Support MVCC (Multi-Versioned Concurrency Con-trol)
Isolation Level– READ_COMMITTED (default)
– REPEATABLE_READ
Locking Mode– Optimistic Lock (default)
– Pessimistic Lock
Key Features: Query
JBoss Hibernate Search + Apache Lucene
Query on values
Index Directory– Lucene Directory: in-memory, file system, JDBC
– Infinispan Directory
Distributed Queries
Key Features: Map/Reduce
Based on Distributed Execution Framework
Mapper, Reducer, Collator, MapReduceTask
JDG, JBoss Data Grid
Red Hat JBoss Data Grid
Infinispan-based

Use Cases
Infinispan on JBoss AS7
Used for WAS clustering, Hibernate L2 cache
Application gets cache with JNDI name us-ing @Resource
Session Clustering
Big Data Real-time Process-ing
