Abstract
In an example embodiment, shards of a database are each stored in in-memory storage as multiple redundant distinct shard instances, but rather than a leader-follower paradigm each redundant shard instance is independent from one another. Each shard contains only an odd number of shard instances, and the number of shard instances is greater than or equal to three. This helps to ensure that enough shard instances are available at any one time to service requests.
