摘要： The present disclosure relates to systems and methods for dynamic sharding of a database comprising data identifiable by keys comprised within a global ordered range. When handling a request for data of at least one key: providing the request to a predetermined shard store; the predetermined shard store verifying, by means of its local subrange collection, whether the at least one key is present in a local subrange of a shard stored on the predetermined shard store; and when at least one key is not present in a local subrange of a shard stored on the predetermined shard store, returning a message comprising the local subrange collection of the predetermined shard store.
