Quick start example.

See QuickStart.java.

Map<Integer, Integer, Void> map =
  MemoryMap
    .functionsOff(intSerializer(), intSerializer())
    .get();

map.put(1, 1); //basic put
map.get(1).get(); //basic get
map.expire(1, Duration.ofSeconds(1)); //basic expire
map.remove(1); //basic remove

//atomic write a Stream of key-value
map.put(Stream.range(1, 100).map(KeyVal::of));

//Create a stream that updates all values within range 10 to 90.
Stream<KeyVal<Integer, Integer>> updatedKeyValues =
  map
    .stream()
    .from(10)
    .takeWhile(keyVal -> keyVal.key() <= 90)
    .map(keyVal -> KeyVal.of(keyVal.key(), keyVal.value() + 5000000));

//submit the stream to update the key-values as a single transaction.
map.put(updatedKeyValues);

//print all key-values to view the update.
map
  .stream()
  .forEach(System.out::println);
