Design patterns and schema design
Schema design in MongoDB is crucial for optimizing performance and scalability. Through the understanding and application of distinct patterns, you can tailor your data model effectively. The following is an overview of various MongoDB design patterns:
- Bucket pattern: This is a great solution for managing streaming data, such as time-series, real-time analytics, or Internet of Things (IoT) applications. It reduces the overall number of documents in a collection, simplifies data access, and improves index performance.
Consider an IoT application where a sensor sends temperature readings every minute. Instead of creating a new document for every reading, the data can be bucketed together in hourly intervals:
{
    "_id": ObjectId("50bf1fbbbcf86cd799439051"),
    "sensor_id": "S123",
    "start_date": ISODate("2023-10-03T08...
