# Regression Detection Suite
#
# This workflow runs under the following conditions:
#    - in the merge queue if any source files were modified, added or deleted.
#    - on demand by a PR comment matching either of:
#      - '/ci-run-regression'
#      - '/ci-run-all'
#      (the comment issuer must be a member of the Vector GH team)
#
# This workflow runs our regression detection experiments, which are relative
# evaluations of the base SHA and head SHA, whose determination depends on how
# the workflow is invoked.
#
# The goal is to give quick-ish feedback on all-up Vector for a variety of configs
# as to whether throughput performance has gone down, gotten more variable in the
# pushed SHA.
#
# Regression detection is always done relative to the pushed SHA, meaning any
# changes you introduce to the experiment will be picked up both for the base
# SHA variant and your current SHA.
#
# Docker image tags are SHA-SHA. The first SHA is the one that triggered this
# workflow, the second is the one of the Vector being tested.
# For comparison images the two SHAs are identical.
