title: Improve performance of MergeRequestsController#ci_environment_status endpoint
merge_request: 30224
author:
type: performance
Remove fallback to project.deployment_platform This improves query performance of MergeRequestsController#ci_environments_status a lot. However this means old deployments that deployed to kubernetes clusters with prometheus installations will no longer show performance metrics as we cannot backfill cluster_id from deployment_platform with certainty (clusters may be edited/added/deleted, which changes the results of deployment_platform). 2019-07-01 04:24:20 -04:00			`---`
