h3. ## Original Dev Problem Removing all docker manifests from a large docker repo seems to take a long time: ~300 manifests takes ~2 minutes ~2000 manifests takes ~30-40 minutes h3. Reproducer: 1. Create and sync a docker repo such as: https://quay.io datawire/ambassador 2. Remove all docker manifests from the repo: pulp-admin docker repo remove manifest --repo-id=1-docker-dev-7915f7d0-7a98-4131-9c41-1be7b578d442 --not id=foo h3. ## Discussion with asmacado * A lot of the delay were caused by the sequential removals * If there was an outage while the task was on-going, the removal was left in a non-deterministic state * The timing model for removal for general use cases grew incredibly fast h3. Solutions with the new refactor: * All BLOBS and MANIFESTS are all removed at once * Higher level units are all removed second * Timing shrank from 300 ~=1hr to 300 ~=a few seconds h3. Concerns: * This refactor would affect removals and syncs * The removal, if interrupted, would leave Orphans which could affect upstream verification verifications h3. Actions: h4. Upstream * Need an upstream verification that ensures there is no change in functionality with remove units and sync units h4. Downstream * Need to verify downstream verification verifications are not affected by this change/patch * BZ verification will just be the removal of a large number of repos takes a short amount of time
