Build-n-Release

FluxPipe is an experimental stand-alone Flux API for serverless workers and embedded datasources
Execute your Flux scripts locally, in serverless functions or anywhere else - decoupled from the data and database.

Fluxpipe runs at 141,6Km/h* and is compatible with InfluxDB 3.0 / IOx, ClickHouse, Grafana and beyond!


InfluxDB Flux is a lightweight scripting language for querying databases and working with data. 1

Demo

Try our serverless demo or launch your own instance to instantly fall in love with flux


Instructions

Download a binary release, docker or build from source

📦 Download Binary

curl -fsSL github.com/metrico/fluxpipe/releases/latest/download/fluxpipe-server -O \
&& chmod +x fluxpipe-server
🔌 Start Server w/ Options
./fluxpipe-server -port 8086

Run with -h for a full list of parameters

🐋 Using Docker

docker pull ghcr.io/metrico/fluxpipe:latest
docker run -ti --rm -p 8086:8086 ghcr.io/metrico/fluxpipe:latest

🐛 Usage

💡 Check out the scripts folder for working examples

Playground

Fluxpipe embeds a playground interface to instantly execute queries (borrowed from ClickHouse 2)


HTTP API

Fluxpipe serves a simple REST API loosely compatible with existing flux integrations and clients

Grafana Flux 1

Fluxpipe is compatible with the native Grafana InfluxDB/Flux datasource (url + organization fields are required!)


⭐ FlightSQL
SQL

You can query InfluxDB 3.0 IOx with raw SQL using the native sql.from handler

import "sql"

sql.from(
    driverName: "influxdb-iox",
    dataSourceName: "iox://iox-server:443/qryn_logs",
    query: "SELECT level, sender, body FROM logs WHERE body LIKE '%DELETE%' limit 10",
)

Flux IOx

You can query InfluxDB 3.0 IOx with Flux using the iox.from handler

import "contrib/qxip/iox"
iox.from(
     bucket: "test",
     host: "eu-central-1-1.aws.cloud2.influxdata.com:443",
     token: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     limit: "10",
     columns: "time, level, sender",
     table: "logs",
     start: -100d,
)

                    _time:time            level:string           sender:string
------------------------------  ----------------------  ----------------------

2023-08-31T00:00:00.091380034Z                    info                 logtest
2023-08-31T00:00:00.091381374Z                    info                 logtest
2023-08-31T00:00:00.091382470Z                    info                 logtest
2023-08-31T00:00:00.091383354Z                    info                 logtest
...

You write data back to InfluxDB 3.0 IOx using the to and wideTo functions

import "contrib/qxip/iox"
import "influxdata/influxdb"
iox.from(
     bucket: "qxip",
     host: "eu-central-1-1.aws.cloud2.influxdata.com:443",
     token: "",
     limit: "10",
     table: "machine_data",
     start: -2d,
 )
 |> range(start: -2d)
 |> aggregateWindow(every: 5s, fn: mean, column: "load", createEmpty: false)
 |> set(key: "_measurement", value: "downsampled")
 |> wideTo(
     bucket: "qxip",
     host: "https://eu-central-1-1.aws.cloud2.influxdata.com",
     token: "",
     orgID: "6a841c0c08328fb1"
    )
⭐ ClickHouse SQL
import "contrib/qxip/clickhouse"

clickhouse.query(
  url: "https://[email protected]",
  query: "SELECT database, total_rows FROM tables WHERE total_rows > 0"
)
|> rename(columns: {database: "_value", total_rows: "_data"})
|> keep(columns: ["_value","_data"])

⭐ LogQL
import "contrib/qxip/logql"

option logql.defaultURL = "http://qryn:3100"
logql.query_range(
     query: "rate({job=\"dummy-server\"}[5m])",
     start: v.timeRangeStart, 
     end: v.timeRangeStop
)
|> map(fn: (r) => ({r with _time: time(v: uint(v: r.timestamp_ns)), _value: float(v: r.value) }))
|> drop(columns: ["timestamp_ns", "value"])
|> sort(columns: ["_time"])
|> group(columns: ["labels"])

⭐ CURL POST

Usage with curl

curl -XPOST localhost:8086/api/v2/query -sS \
  -H 'Accept:application/csv' \
  -H 'Content-type:application/vnd.flux' \
  -d 'import g "generate" g.from(start: 2022-04-01T00:00:00Z, stop: 2022-04-01T00:03:00Z, count: 3, fn: (n) => n)'

Secrets

Flux builds using EnvironmentSecretService accessing system environment variables from flux scripts.

import "influxdata/influxdb/secrets"
key = secrets.get(key: "ENV_SECRET")

STDIN CMD

Fluxpipe can be used as a command-line tool and stdin pipeline processor

Generate CSV
echo 'import g "generate" g.from(start: 2022-04-01T00:00:00Z, stop: 2022-04-01T00:03:00Z, count: 5, fn: (n) => 1)' \
| ./fluxpipe-server -stdin
Parse CSV
cat scripts/csv.flux | ./fluxpipe-server -stdin
Query SQL
cat scripts/sql.flux | ./fluxpipe-server -stdin
