Import and export data into/from InfluxDB

About

You can use influxio to import and export data into/from InfluxDB. It can be used both as a standalone program, and as a library.

influxio is, amongst others, based on the excellent dask, fsspec, influxdb-client, influx-line, line-protocol-parser, pandas, and SQLAlchemy packages.

Please note that influxio is alpha-quality software, and a work in progress. Contributions of all kinds are very welcome, in order to make it more solid. Breaking changes should be expected until a 1.0 release, so version pinning is recommended, especially when you use it as a library.

Synopsis

# Export from API to database.
influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "sqlite://export.sqlite?table=demo"

# Export from data directory to line protocol format.
influxio copy \
    "file:///path/to/influxdb/engine?bucket-id=372d1908eab801a6&measurement=demo" \
    "file://export.lp"

Quickstart

If you are in a hurry, and want to run influxio without any installation, just use the OCI image on Podman or Docker.

docker run --rm --network=host ghcr.io/daq-tools/influxio \
    influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "crate://crate@localhost:4200/testdrive/demo"

Setup

Install influxio from PyPI.

pip install influxio

Usage

This section outlines some example invocations of influxio, both on the command line, and per library use. Other than the resources available from the web, testing data can be acquired from the repository’s testdata folder.

Prerequisites

For properly running some of the example invocations outlined below, you will need an InfluxDB and a CrateDB server. The easiest way to spin up those instances is to use Podman or Docker.

Please visit the docs/development.rst documentation to learn about how to spin up corresponding sandbox instances on your workstation.

Import

# From test data to API.
# Choose one of dummy, mixed, dateindex, wide.
influxio copy \
    "testdata://dateindex/" \
    "http://example:token@localhost:8086/testdrive/demo"

# With selected amount of rows.
influxio copy \
    "testdata://dateindex/?rows=42" \
    "http://example:token@localhost:8086/testdrive/demo"

# With selected amount of rows and columns (only supported by certain test data sources).
influxio copy \
    "testdata://wide/?rows=42&columns=42" \
    "http://example:token@localhost:8086/testdrive/demo"

# From line protocol file to InfluxDB API.
influxio copy \
    "file://tests/testdata/basic.lp" \
    "http://example:token@localhost:8086/testdrive/demo"

# From line protocol file to InfluxDB API.
influxio copy \
    "https://github.com/influxdata/influxdb2-sample-data/raw/master/air-sensor-data/air-sensor-data.lp" \
    "http://example:token@localhost:8086/testdrive/demo"

# From line protocol file to any database supported by SQLAlchemy.
influxio copy \
    "file://export.lp" \
    "sqlite://export.sqlite?table=export"

Export from API

# From API to database file.
influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "sqlite:///export.sqlite?table=demo"

# From API to database server.
influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "crate://crate@localhost:4200/testdrive?table=demo"

# From API to line protocol file.
influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "file://export.lp"

# From API to line protocol on stdout.
influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "file://-?format=lp"

Export from Cloud to Cloud

# From InfluxDB Cloud to CrateDB Cloud.
influxio copy \
    "https://8e9ec869a91a3517:T268DVLDHD8AJsjzOEluu...Pic4A==@eu-central-1-1.aws.cloud2.influxdata.com/testdrive/demo" \
    "crate://admin:dZ,Y18*Z...7)[e-mail]:4200/testdrive/demo?ssl=true"

crash \
    --hosts 'https://admin:dZ,Y18*Z...7)[e-mail]:4200' \
    --command 'SELECT * FROM testdrive.demo;'

Export from data directory

# From InfluxDB data directory to line protocol file.
influxio copy \
    "file:///path/to/influxdb/engine?bucket-id=372d1908eab801a6&measurement=demo" \
    "file://export.lp"

# From InfluxDB data directory to line protocol file, compressed with gzip.
influxio copy \
    "file:///path/to/influxdb/engine?bucket-id=372d1908eab801a6&measurement=demo" \
    "file://export.lp.gz"

# From InfluxDB data directory to line protocol on stdout.
influxio copy \
    "file:///path/to/influxdb/engine?bucket-id=372d1908eab801a6&measurement=demo" \
    ""file://-?format=lp"

OCI

OCI images are available on the GitHub Container Registry (GHCR). In order to run them on Podman or Docker, invoke:

docker run --rm --network=host ghcr.io/daq-tools/influxio \
    influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "stdout://export.lp"

If you want to work with files on your filesystem, you will need to either mount the working directory into the container using the --volume option, or use the --interactive option to consume STDIN, like:

docker run --rm --volume=$(pwd):/data ghcr.io/daq-tools/influxio \
    influxio copy "file:///data/export.lp" "sqlite:///data/export.sqlite?table=export"

cat export.lp | \
docker run --rm --interactive --network=host ghcr.io/daq-tools/influxio \
    influxio copy "stdin://?format=lp" "crate://crate@localhost:4200/testdrive/export"

In order to always run the latest nightly development version, and to use a shortcut for that, this section outlines how to use an alias for influxio, and a variable for storing the input URL. It may be useful to save a few keystrokes on subsequent invocations.

docker pull ghcr.io/daq-tools/influxio:nightly
alias influxio="docker run --rm --interactive ghcr.io/daq-tools/influxio:nightly influxio"
SOURCE=https://github.com/daq-tools/influxio/raw/main/tests/testdata/basic.lp
TARGET=crate://crate@localhost:4200/testdrive/basic

influxio copy "${SOURCE}" "${TARGET}"
