What
A database architecture that partitions data by key ranges and distributes the data among two or more database instances. Sharding enables horizontal scaling. See Sharding.
splitting and storing a single logical dataset in multiple databases. By dividing a large dataset into smaller, more manageable parts, sharding can help to improve the speed and performance of database queries.
How
- Choose a sharding key
- a field that can be used to distribute data evenly across shards.
- Create Shards
- Each shard is a self-contained database that holds a portion of the total dataset.
- Distribute Data
- Use the sharding key to distribute data evenly across your shards.
