Sharding¶
Sharding distributes a
single logical database system across a cluster of machines. Sharding
uses range-based portioning to distribute documents
based on a
specific shard key.
This page lists the documents, tutorials, and reference pages that
describe sharding.
For an overview, see Sharding Fundamentals. To configure, maintain, and
troubleshoot sharded clusters, see Sharded Cluster Administration. For
deployment architectures, see
Sharded Cluster Architectures. For details on the
internal operations of sharding, see Sharding Internals.
For procedures for performing certain sharding tasks, see the Tutorials
list.
