We are planning to implement Encryption at rest using WiredTired Storage Engine
What is the percentage of disk space increase that would be required to account for after the encryption .
I am aware the Encryption at rest is wrapper for the Entire DB volume and the individual collections and fields are not encrypted as such …
Should the disk space increase ( if it does) be any concern for Encryption at rest
Similarly for Field level encryption , what is percentage of additional disk space that need to be accounted for ( For Eg : for a 1TB Mongodb Database)
