Clean Up Old Data Automatically with MongoDB TTL Indexes
With Big Data, comes well … a lot of data. But what if some of that data is only really useful within a certain timeframe? Think about things like: Luckily, MongoDB makes it easy to keep your collections tidy with what are called TTL indexes. TTL (Time To Live) indexes automatically delete documents after a…

Scaling MongoDB with Sharding: Setup Best Practices
In our previous post, we covered the basics of sharding (how MongoDB distributes data across multiple servers), why config servers are critical, and how balancing helps maintain efficiency. Now, we’ll go deeper into three critical areas that will determine whether your sharded cluster thrives or struggles: Let’s break these down in detail. Shard Key Selection:…

Scaling MongoDB with Sharding: The Basics
When your database starts to outgrow its capacity, you’ve got two options: scale up or scale out. Scaling up means buying bigger, beefier servers with more RAM, CPU, and disk space. Whereas scaling out (using MongoDB’s sharding feature) can be a more cost-effective and flexible solution. The Basics of Sharding In simple terms, sharding involves…

MongoDB Aggregations: Identifying Popular Ingredients with $unwind and $group
In this series, we’re exploring different MongoDB aggregation operators by applying them to a collection of recipes. MongoDB Aggregations Series As part of our exploration we are imagining you’re building a recipe website. Today we want to analyze ingredient usage across all our recipes to find the most common ingredients. By using MongoDB’s $unwind and…

MongoDB Aggregations: Finding Cooking Times with $min and $max
In this series we will explore different operators in the MongoDB Aggregation Framework via the context of a collection of recipes. MongoDB Aggregations Series Let’s say we’re making a brand new recipes website. Knowing the cooking times can help us categorize recipes into quick meals, slow-cooked dishes, or anything in between. MongoDB’s $min and $max…

Understanding the local Database in MongoDB
When you set up and initiate a replica set in MongoDB, all databases and collections on the primary database are replicated to the secondary nodes. However, there is one crucial exception: the local database. What is the local Database? Each mongod instance maintains its own unique copy of the local database. It contains collections that…
