MongoDB's ObjectId contains a timestamp, which can help you filter documents based on their creation date. To reduce the size of your collection, you can use a strategy that involves deleting or archiving old documents based on a specific date or time range.
Here's a high-level overview of the process:
- Determine the date threshold: Decide on a date or time range beyond which you would like to remove or archive the documents. For example, you might want to remove documents older than 6 months or 1 year.
- Query documents based on the ObjectId's timestamp: You can use MongoDB's aggregation framework or the find() method to filter documents based on the creation date embedded in the ObjectId.
