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. Cassandra, Solr)
• Advisory role for porting into other systems (e.g. Postgres, Cassandra's off-heap)

Version 2.1

• Maintain zero weight entries in a dedicated queue
• Evaluate incremental (instead of periodic) W-TinyLFU reset
• Understand why fastpath (disabled) was slower when enabled
• Explore a bounded write queue to throttle writes (for synthetic tests)

Future

• Collections
  • MPSC linked array queue [slides]
  • Review ConcurrentLinkedStack for promotion out of Beta status (or deletion)
• Future JDKs
  • JDK 9: Migrate usages of sun.misc.Unsafe to VarHandles
  • 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?)
