Blocker Description
at_plus consistency requires a scan vector. However to support multi bucket queries, SDK needs to pass scan_vectors for each bucket so cases like JOIN or UNION of multiple buckets can adhere to RYOW under operations spanning multiple buckets.
EX:
SELECT * FROM bucket1 JOIN bucket2 ON KEY ... FOR ...
SELECT * FROM bucket1 UNION SELECT * FROM bucket2 ...
with these queries, we need the fully qualified scan_vector (namespace:keyspace/bucket:scan_vector) for each bucket.
