@vvbalaji we cannot enable encryption on a running alpha. The alpha has to be restarted with the encryption key. The changes in GitHub - dgraph-io/badger at ibrahim/encryption-keyregistry a will read a file and recreate then file. The CPU/memory usage won’t be affected. This is similar to deleting a file and recreating it. Also, until badger starts, dgraph cannot serve queries/mutations. The overhead of GitHub - dgraph-io/badger at ibrahim/encryption-keyregistry is negligible.
