Principles of Sharding for Relational Databases - Citus Data

A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard is held on a separate database server instance, to spread load. Some data within a database remains present in all shards, but some appear only in a single shard. Each shard (or server) acts as the single source for this subset of data. WebbClustered SQL RDBMS's can scale reads by introducing additional nodes in the cluster. There are constraints to how far read operations can be scaled, but these are imposed by the difficulty of scaling up writes as you introduce more nodes into the cluster.
