Experimental, unoptimized InfluxDB API to Clickhouse DB Gateway prototype for Timeseries.

Unstable, Experimental, Dangerous! Do not use this!

Usage

Start Server

CLICKHOUSE_SERVER=my.clickhouse.server npm start

The server attempts emulating an InfluxDB API instance and can accept line protocol and query requests from Telegraf, Chronograf, Kapacitor and potentially clients with (extremely) basic features.

POST Metrics /write

The /write endpoint expects HTTP POST data using the InfluxDB line protocol:

<measurement>[,<tag_key>=<tag_value>[,<tag_key>=<tag_value>]] <field_key>=<field_value>[,<field_key>=<field_value>] [<timestamp>]

Example

 curl -d "statistics_method,cseq=OPTIONS 100=1,OPTIONS=1 1545424651000000000" \
      -X POST 'http://localhost:8686/write?db=mystats'
