Infinispan details

• developed & provided by JBoss
• Open Source license
• distributed, in-memory data structure
• High Available: configuration options depending on your safety / performance considerations
  • Total replication
  • Partial replication ("distribution mode")
• Elastic:
  • easy to scale up / down
  • deal with node stops / crashes
  • accept additional nodes
  • managed through JGroups

Capabilities:

• Transactions
• Map / Reduce
• Query
• JMX access

Two access modes to inifinispan:

• embedded mode: in the JVM
• client / server mode: different protocols supported:
  • REST
  • memcached
  • hotrod

Possible setups:

• local cache: Simple Map-like interface, with advanced cache-features (eviction, etc.)
• cluster cache: all caches are kept in sync between JVM's, the developer is responsible for accessing the persistence layer (DB)
• grid cache: the cache itself handles the persisting of the data to the DB.

JGroups

• reliable cluster communication
• developed by JBoss, and used by Infinispan
• Node / cluster config (incl. auto-discover setup)
• focus on performance: e.g. UDP, but with reliability handled by JGroups
• support for reliable multicast messages
