sharding
n.n. a way of splitting a large database into smaller, faster pieces. Each piece, called a shard, is stored on a different server to help the system handle more work.
n. a database architecture pattern that involves horizontal partitioning of data across multiple independent servers or nodes. Each partition, or shard, contains a subset of the total dataset to improve scalability and performance.
The company used sharding to manage their massive user database.
As the application grew to millions of active users, the engineering team implemented sharding to prevent a single database server from becoming a bottleneck.
While sharding significantly increases the write throughput of a distributed system, it introduces substantial complexity regarding cross-shard queries and data consistency across the network.
Commonly used in the context of distributed systems and database administration.
