Concurrent map primitives implementation

[Avery Ching]

Hi, I stumbled onto your project and was thinking about using it in Apache Giraph (Iterative graph processing on Hadoop) giraph.apache.org.  I was wondering whether you intend to support primitive collections for concurrent maps (i.e. [keyType][valueType]ConcurrentMap).

[Dawid Weiss]

Not really. These are very specific data structures for very specific
needs. You may want to check out with fastutil and whether Sebastiano
has implemented something that would be update-save for concurrent
threads. Depending on the problem a memory-mapped buffer may also turn
out to be a nice synchronization primitive (even for inter-process
communication). Peter Lawrey's Chronicle implements some of these
concepts, for instance.
