Bran-read
Service which provides the statistics of messages, threads, containers and others. Used by the API.
Downtime
Not critical
If Bran-read service is down then thread and message statistics will not be available.
Scaling
Scalable to any reasonable amount.
Deployment
Use rolling release. Update pods one by one.
Strong dependencies
Bran-read strongly depends on the Clickhouse. It will not start without it.
