Roadmap

Current

The focus is on helping users adopt the library or port its ideas into their custom solutions. In particular that means a keen interest in,

• Fixing bugs and listening to user feedback
• Integration into popular frameworks (e.g. Spring)
• Adoption by database and search products (e.g. HBase, Solr)
• Advisory role for porting into other systems (e.g. Postgres, Cassandra's off-heap)

Version 2.x

• Maintain zero weight entries in a dedicated queue
• Add CacheLoder reloadAll for batch refresh (#7)
• Support variable expiration (via hierarchical wheel timer)

Version 3.0

• Remove deprecated classes and methods
• JDK 9: Migrate usages of sun.misc.Unsafe to VarHandles
• Return the refresh future to allow the caller to block on the reload (143)
• Propagate invalidations to CacheWriter delete when the entry is not present in the cache

Future

• Future JDKs
  • JDK 10: Determine how to best leverage Value Types
• Google Guava
  • Work with the Google team as they embrace JDK 8 and determine the future of Guava's Cache (deprecated?)
