Migration from influxDB-Python

[cfarsbot]

Is there any migration guide, when comming from influxDB-Python?
Currently i am on Influx 1.8, but wanna switch to Influx 2
So just staying isn't an option.

For example, i'm missing functions like
influxdb_client.line_protocol
drop_database / create_database
Is there any documentation what the equivalent would be?

Hi @cfarsbot,

Is there any migration guide, when comming from influxDB-Python?

there isn't the migration guide. Is this something you might be willing to help with?

For example, i'm missing functions like
influxdb_client.line_protocol

You can use Point data structure to construct LineProtocol:

• influxdb-client-python/influxdb_client/client/write/point.py

  Line 45 in a421a6f

  class Point(object):

• https://github.com/influxdata/influxdb-client-python#synchronous-client

drop_database / create_database

The InfluxDB 2 uses Bucket concept instead of Databases. Here is an example how to manage buckets:

I'm also migrating from 1.8 towards 2.0. My first step has been to migrate from the old to this new client. To replace the create/drop database functions (That I use in my test suite) I call the endpoint directly with:

response = requests.post(
    "http://localhost:8086/query", data={"q": "CREATE DATABASE db"}
)
response.raise_for_status()

Or DROP DATABASE to drop. Change localhost to your server's url. My test db has no password, if you have auth you can use it via requests as well.

I have a follow up question on this, in older version I am able to use get_points() function to get back Point objects from query results.
In comparison in the new version query_api().query(".......") returns a list of Flux records and how do I get back Point objects from it?

@yasspoint, unfortunately we don't have a helper to transform FluxRecord to Point
