unknown
timestamp	Use timestamp conflict resolution. Timestamp-based conflict resolution (often referred to as Last Write Wins, or LWW) uses the document timestamp (stored in the CAS) to resolve conflicts. The timestamps associated with the most recent updates of source and target documents are compared. The document whose update has the more recent timestamp prevails.
sequence_number	Use sequence number conflict resolution. Conflicts can be resolved by referring to documents' sequence numbers. Sequence numbers are maintained per document, and are incremented on every document-update. The sequence numbers of source and target documents are compared; and the document with the higher sequence number prevails.
custom	VOLATILE: This API is subject to change at any time. In Couchbase Server 7.1, this feature is only available in "developer-preview" mode. See the UI XDCR settings.

unknown
full	During ejection, everything (including key, metadata, and value) will be ejected. Full Ejection reduces the memory overhead requirement, at the cost of performance. This value is only valid for buckets of type COUCHBASE.
value_only	During ejection, only the value will be ejected (key and metadata will remain in memory). Value Ejection needs more system memory, but provides better performance than Full Ejection. This value is only valid for buckets of type COUCHBASE.
no_eviction	Couchbase Server keeps all data until explicitly deleted, but will reject any new data if you reach the quota (dedicated memory) you set for your bucket. This value is only valid for buckets of type EPHEMERAL.
not_recently_used	When the memory quota is reached, Couchbase Server ejects data that has not been used recently. This value is only valid for buckets of type EPHEMERAL.
