The types of keys that a ProfileObject can have. Each ProfileObject can have only 1 UNIQUE key but multiple PROFILE keys. PROFILE, ASSET, CASE, or ORDER means that this key can be used to tie an object to a PROFILE, ASSET, CASE, or ORDER respectively. UNIQUE means that it can be used to uniquely identify an object. If a key a is marked as SECONDARY, it will be used to search for profiles after all other PROFILE keys have been searched. A LOOKUP\$1ONLY key is only used to match a profile but is not persisted to be used for searching of the profile. A NEW\$1ONLY key is only used if the profile does not already exist before the object is ingested, otherwise it is only used for matching objects to profiles.
