Welcome to our MongoDB Replication and Sharding tutorials section. This guide will help you understand the concepts and implementation of MongoDB replication and sharding.

What is Replication?

Replication in MongoDB provides high availability and data redundancy. It involves copying data from one MongoDB server (known as the primary) to one or more secondary servers. If the primary server fails, one of the secondaries can automatically take over as the new primary.

  • Replication Process:
    • Data changes made on the primary are propagated to the secondaries.
    • Secondaries can take over as the primary in case of a primary failure.

What is Sharding?

Sharding in MongoDB is the process of distributing data across multiple servers to provide horizontal scalability. It allows handling large amounts of data and high throughput.

  • Sharding Process:
    • Data is split into smaller chunks called "shards".
    • Shards are distributed across multiple servers.
    • Queries can be executed on any shard containing relevant data.

Getting Started with Replication and Sharding

Before diving into the tutorials, ensure you have MongoDB installed and configured on your system.

Tutorials

1. Setting Up Replication

This tutorial guides you through setting up a basic replication setup with one primary and two secondaries.

2. Configuring Shards

Learn how to configure and manage shards in a MongoDB cluster.

3. Replication Monitoring

Monitor your MongoDB replication setup to ensure everything is working correctly.

4. Scaling with Sharding

FAQs

  • What is the difference between replication and sharding?

    • Replication provides data redundancy and high availability, while sharding allows horizontal scalability for large datasets.
  • How many secondaries should I have in my replication setup?

    • It's recommended to have at least two secondaries for high availability and data redundancy.
