Does AWS KMS provides KMIP communication protocol to transfer these keys to the mongodb server.
How can I pass following parameters to mongodb config file
See the security options on the MongoDB configuration section for information.
Also, Encryption At Rest is available only in MongoDB Enterprise edition - a commercially supported product. If your company has a commercial subscription and have further questions about the feature I would suggest to open a case in Commercial Support Portal.
Alternatively if you are evaluating MongoDB Enterprise and is interested, feel free to send me a private message of your contact details and I can request a MongoDB Account Executive to reach out.
