Hibernate 4 Memcached Second Level Cache Implementation

Current stable version

0.7

ChangeLog

Requirements

• Java 6 or higher
• Hibernate 4.2 or higher
• Tested with hibernate 4.2.12

Features

• Supported memcached library
  • spymemcached
• Supported concurrency strategy
  • READ_ONLY
  • NONSTRICT_READ_WRITE : recommended
• Region(Namespace) support : Memcached does not have region concept, but this library supports regions. Refer to Memcached Namespace
• Shortening query cache key : When you use query cache, the query cache key is too long for memcached key(max 250). So the key is shortened by MD5 + hashCode().
• Many type of memcached adapters : You can add your own memcached adapter. I may add xmemcached, couchbase adapters.

Known Issues

• DO NOT USE Query Cache with Hibernate Multi Tenancy #15
