Hashed Sharding Output
Assuming we have a sharded collection named “mycollection” with hashed sharding on the “myShardKeyField” field, querying the data will produce output similar to the following:
{
"_id": ObjectId("60f9d7ac345b7c9df348a86e"),
"name": "John Doe",
"age": 30,
"myShardKeyField": "someValue"
}
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.
