For Single Collection Creation with Pre-image support👩🏼🤝👨🏻
We'll write commands to this area. Just drag it up.
Step 1: Switch to the database where you want to create your collections 🔁
use <db-name> // use to switch your database
Step 2: Execute the following command to create the collection with pre-image support 🫂
db.createCollection("<collection-name>", {changeStreamPreAndPostImages: {enabled: true}})
As you can see my new collection has been created with pre-image support
Alternatively, If you need to create multiple collections with pre-image support then follow the steps🥷:
Doing these steps again and again for multiple collections is not ideal. There's a better way to do this.
You can use JavaScript forEach method to create multiple collections in one go.
["coll1", "coll2", "coll3", "coll4", "coll5"].forEach(collection => db.createCollection(collection, {changeStreamPreAndPostImages: {enabled: true}}))
As you can see, multiple collections with pre-image support has been created successfully
Conclusion 🥱
It's very important to enable pre-image support sometimes while using triggers. If you know these methods then our life become a lot easier sometimes.
