The config file documentation still mentions KeyDB Enterprise

[SpecLad]

From https://docs.keydb.dev/docs/config-file/:

# Enable Enterprise?  KeyDB Enterprise provides support for Enterprise only features
#   note: you may omit the license key to demo Enterprise features for a limited time
# enable-enterprise [License Key]

# Enable FLASH support? (Enterprise Only)
# storage-provider flash /path/to/flash/db

As far as I understand, Enterprise doesn't exist any more.
