14:project: glance
15
16:problem: Individual glance nodes are fully un-aware that there might be
17 other nodes operating in the same space. This lack of communication
18 between the nodes causes issues separating workers and operating in
19 different locations.
20
21:solution: We have message queues already utilized in notifications and other
22 projects. Lets expand that for communications between different
23 glance-api nodes to gain better operational efficiency.

28 Optional sections -- delete any that don't apply to this spec lite
29
30:alternatives: We could use something else than the message queues but
31 effectively that would end up recreating something like registry
32 but just as a message broker.
33
34:timeline: Possible initial functionality in Rocky, more use cases covered S
35 and beyond. This can be expanded fairly easily so we can proceed as
36 time permits.
