Announcing VoltDB 4.0: Enhanced In-Memory Analytics and Online Elasticity

Wednesday, January 29, 2014

  2. It needs to be able to query player status and ranking. Each player’s ranking in relation to other players, for example, needs to be computed regularly, across all players and all games.
  3. It would need to support
