To create a TTL (Time-To-Live) index on a long timestamp field in MongoDB, follow these steps:

  1. Connect to your MongoDB database using a MongoDB client or shell.
  2. Select the database and collection where you want to create the TTL index.
  3. Run the following command to create the TTL index on the long timestamp field:
1
db.yourCollection.createIndex({ "timestampField": 1 }, { expireAfterSeconds: 0 })


Replace "yourCollection" with the name of your collection and "timestampField" with the name of the long timestamp field on which you want to create the TTL index.

  1. The expireAfterSeconds option specifies the time in seconds after which the documents will expire and be automatically removed from the collection. Set it to 0 if you want to use the timestamp value in milliseconds as the expiration time.
  2. Once the TTL index is created, MongoDB will automatically delete documents from the collection where the timestamp field is older than the specified time.


Make sure to test the TTL index behavior and expiration settings to ensure it works as expected for your use case.
