Special notes for your reviewer:

Checklist

  • Reviewed the CONTRIBUTING.md guide (required)
  • Documentation added
  • Tests updated
  • Title matches the required conventional commits format, see here
    • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
  • Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
  • If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR

I renamed this field as now we have a number of *ring_client.Pool.

if factory == nil {
factory = ring_client.PoolAddrFunc(func(addr string) (ring_client.PoolClient, error) {
return client.New(clientCfg, addr)
ingesterClientFactory := cfg.factory
