What is a Hashed Sharding?
Hashed sharding is a sharding strategy in MongoDB that uses a hash function to determine which shard a document belongs to based on the value of a specified field. This hash function calculates a hash key for the field value, and MongoDB uses this hash key to distribute documents evenly across shards.
Hashed Sharding in MongoDB
Sharding is a fundamental concept in MongoDB that allows for horizontal scaling of databases by distributing data across multiple servers. Hashed sharding is a specific sharding strategy that uses a hash function to determine how data is distributed among shards. In this article, we’ll delve into the concept of hashed sharding in MongoDB, covering its principles, and implementation, and providing beginner-friendly examples with outputs to illustrate its effectiveness.
