      New APIs are available on KeyValueStore.

      Optimized storage of Long values:

      • put(String key, Long value)
      • put(String key, Long value, long ttl)
      • getLong(String key)
      • getLongs(Collection<String> keys)

      Atomic increment:

      • addAndGet(String key, long delta)

      Description

      In order to improve atomic increments in the Key/Value store, it would be better to provide this API directly instead of having the caller rely on manual compareAndSet.

      In order to increment efficiently in MongoDB, this will also require extending the values data model to allow long values in addition to the current byte[] and String.

      This would allow the implementation of a KeyValueUIDSequencer that would therefore not depend on a specific storage backend.
