Description

An in-flight operation may not be seen by the new GII requester if the GII provider cache closes. This happens when there are more than one replica for the region.

Scenario:

There are 3 nodes (N1 with primary bucket, N2 with secondary bucket and N3 new node doing GII request)

• accessor begins putAll
• accessor sends putAll to N1
• N1 locally processes putAll
• N1 attempts to replicate putAll to N2
• during this putAll, N1 is shutdown normally
• during this putAll (after N1 has started to shutdown), N3 attempts to GII from N1
• it fails because N1 is shutting down
• N3 then GIIs from N2 (but before the put is received by it)
• after GII, N3 doesn't have the entry, but N2 does
• accessor completes putAll successfully
