Summary
When Kong 2.1.0 was release we needed to add special workaround to enable blue-green deployment with the introduction of workspaces.
We needed to add special
select_by_cache_key
toPlugins
DAO. The check that we added is hurting the Kong performance, as seen reported in #8788. We got further PR from the author with #8789. While the fix is good, I do think we can remove this by now altogether. The only downside of this, is that for people who migrate directly from Kong < 2.1.x to3.0.0
, we don't support the blue-green deployment.Issues Resolved
