Hi, thanks for a great article, please do write more!
I have a question, though:
In “Replication After Ingest” pattern you mention
But here’s a little-known fact about subscriptions: They can send data anywhere you want over HTTP or UDP.
However, subscriptions don’t contain authentication information in their HTTP requests. This makes it impossible to use for data replication between 2 clusters with enforced HTTP authentication (unless, I’m missing something).
For the time being, this could be worked around using Telegraf as a proxy with http_listener input and influxdb output for each subscription, and with filters applied, Telegraf will route metrics to the proper database. But this workaround introduces extra moving part and a replication delay roughly equal to Telegraf’s interval.
Are there any plans to add authentication support for HTTP subscriptions in future? Would it be a part of OSS version, or InfluxEnterprise?
