How Sharding Works in MongoDB
Sharding in MongoDB involves three main components:
- Shards: These are the individual servers that store subsets of the data.
- Config Servers: These servers store the metadata and configuration settings for the cluster, including information about the data distribution.
- Query Routers (Mongos): These servers direct the queries from applications to the appropriate shard(s).
How to Perform Horizontal Scaling in MongoDB?
Horizontal scaling, also known as scaling out, involves adding more servers to a database system to handle increased load. In the context of MongoDB, horizontal scaling is implemented through a process called sharding. This article will delve into the details of horizontal scaling in MongoDB, discussing what it is, how it works, and the steps to set it up.
