Key.userKey Field

Original user key. This key is immediately converted to a hash digest. This key is not used or returned by the server by default. If the user key needs to persist on the server, use one of the following methods:

• Set "WritePolicy.sendKey" to true. In this case, the key will be sent to the server for storage on writes and retrieved on multi-record scans and queries.
• Explicitly store and retrieve the key in a bin.
