# `Required Checks` is the aggregator job at the bottom of

# .github/workflows/ci.yml. It is deliberately the only entry: the

# individual heavy jobs publish a different check name depending on

# whether they ran or were skipped, so none of them can be required

# directly. dev/ci/check-ci-config.py keeps this string in sync with

# the job's `name:`.

#

# Careful when editing this list. A context that never reports blocks

# every merge to main, including the merge that would fix this file,

# and recovering from that needs an INFRA Jira ticket.

# GitHub's merge queue. Classic `protected_branches` above has no way to

# express this, but .asf.yaml rulesets accept a raw Rulesets API payload, so

# no INFRA ticket is needed. Same approach as apache/iceberg-python and

# apache/seatunnel; GitHub evaluates rulesets and classic branch protection

# together and applies the most restrictive result.

#

# Only the default branch is queued. Merge queue rules do not support

# wildcard ref patterns, so the branch-N.M release branches keep plain

# branch protection.

# Matches enabled_merge_buttons above: squash is the only method

merge_method: SQUASH

# ALLGREEN: every entry's own build has to be green, not just the

# last one's. HEADGREEN would let an entry whose build failed ride

# in on a green head, which papers over a flake but equally papers

# over a real failure that a later entry happens to mask. It would

# also let untested code in: `merge_group.base_sha` is the queue

# commit of the entry ahead, so each entry's build runs only the

# suites its own changed files select, and a green head says

# nothing about the suites an earlier entry needed.

grouping_strategy: ALLGREEN

# Speculation depth: how many merge_group builds run at once. Each

# queue entry gets its own build of itself plus everything ahead of

# it, and merge limits do not combine those builds, so this is the

# throughput dial. In September 2026 a full pipeline took a median

# of 92 minutes, so 2 capped a queue that never ran dry at roughly

# 30 merges a day while approvals arrived at about 20 a day, and

# the backlog grew. 4 roughly doubles the cap. The price is that

# many concurrent pipelines, and more rebuilds when an entry fails,

# since every entry behind it that was already building restarts.

max_entries_to_build: 4

# they do not batch the builds. No minimum and no wait, so a lone
