Derek Menteer 04edace1de Fix issue with streaming service health watches. (#17775) ... Fix issue with streaming service health watches. This commit fixes an issue where the health streams were unaware of service export changes. Whenever an exported-services config entry is modified, it is effectively an ACL change. The bug would be triggered by the following situation: - no services are exported - an upstream watch to service X is spawned - the streaming backend filters out data for service X (due to lack of exports) - service X is finally exported In the situation above, the streaming backend does not trigger a refresh of its data. This means that any events that were supposed to have been received prior to the export are NOT backfilled, and the watches never see service X spawning. We currently have decided to not trigger a stream refresh in this situation due to the potential for a thundering herd effect (touching exports would cause a re-fetch of all watches for that partition, potentially). Therefore, a local blocking-query approach was added by this commit for agentless. It's also worth noting that the streaming subscription is currently bypassed most of the time with agentful, because proxycfg has a `req.Source.Node != ""` which prevents the `streamingEnabled` check from passing. This means that while agents should technically have this same issue, they don't experience it with mesh health watches. Note that this is a temporary fix that solves the issue for proxycfg, but not service-discovery use cases.		1 year ago
