MongoDB Compact Structured Encryption Data

MongoDB Compact Structured Encryption Data

In MongoDB, the compactStructuredEncryptionData operation is used to reduce the storage footprint of encrypted data in a collection. This method is essential for optimizing storage and improving performance when using structured encryption in MongoDB collections.

Syntax

db.collection.compactStructuredEncryptionData(options)

The compactStructuredEncryptionData method compacts encrypted data within a collection. The options parameter can be used to customize the compaction process.

Example MongoDB Compact Structured Encryption Data

Let's look at an example of how to use the compactStructuredEncryptionData method in the programGuru collection in MongoDB:

1. Compact Structured Encryption Data

db.programGuru.compactStructuredEncryptionData({})

This command compacts the encrypted data in the programGuru collection with default options.

Full Example

Let's go through a complete example that includes switching to a database, creating a collection, inserting encrypted documents, and compacting the structured encryption data.

Step 1: Switch to a Database

This step involves switching to a database named myDatabase.

use myDatabase

In this example, we switch to the myDatabase database.

Step 2: Create a Collection

This step involves creating a new collection named programGuru in the myDatabase database.

db.createCollection("programGuru")

Here, we create a collection named programGuru.

Step 3: Insert Encrypted Documents into the Collection

This step involves inserting encrypted documents into the programGuru collection.

db.programGuru.insertMany([
    { name: "John Doe", age: 30, email: "john.doe@example.com" },
    { name: "Jane Smith", age: 25, email: "jane.smith@example.com" },
    { name: "Jim Brown", age: 35, email: "jim.brown@example.com" }
])

We insert multiple encrypted documents into the programGuru collection.

Step 4: Compact Structured Encryption Data

This step involves using the compactStructuredEncryptionData method to compact the encrypted data in the programGuru collection.

db.programGuru.compactStructuredEncryptionData({})

We compact the encrypted data in the programGuru collection with default options.

Step 5: Verify the Compaction

This step involves querying the programGuru collection to verify that the structured encryption data has been compacted.

db.programGuru.find().pretty()

This command retrieves all documents from the programGuru collection and displays them in a readable format.

Conclusion

The MongoDB compactStructuredEncryptionData operation is crucial for optimizing the storage and performance of encrypted data within collections. Understanding how to use this method allows you to efficiently manage and maintain encrypted data in MongoDB.
