Datalake scripts

How to use

Installation

With Python 3.6+:

$ pip install datalake-scripts
$ pip3 install datalake-scripts

Using as a library

see the following link

Using as a CLI

The cli can be used with:

$ ocd-dtl <command> <parameter>

Check ocd-dtl -h for help, including the list of commands available.

You can also use a script directly by using the following command: <script_name> <script_options>.

/!\ Make sure to use utf-8 without BOM when providing a file (-i option)

Environment variables

Authentication

There are two methods of authentication:

• The first one is the use of the username and password. Every request to the API, will then use fresh tokens periodically created with these credentials.
• The second one is the use of a long term token. You can create long term token through the GUI, it can have more restricted permissions than your account. You can create several long term tokens for one account.

In case you don't want to enter credentials for each commands and you are on a secured terminal, set those variables:

• OCD_DTL_LONGTERM_TOKEN a long term token associated to your Datalake account. Please note that if this variable is set, then the long term token will be used for every request to the Datalake API, even if you set the username and passsword environment variables below. This is important because some endpoints / requests do not accept long term tokens but need fresh tokens (ie a Datalake instance with username and password). Check for the need of fresh tokens in each endpoint description here

or

• OCD_DTL_USERNAME email address used to login on Datalake API/GUI.
• OCD_DTL_PASSWORD password used to login on Datalake API/GUI.

These last two are independent and one can be used without the other if you wish.

Throttling

For throttling the request, those two environment variable can be used:

• OCD_DTL_QUOTA_TIME define, in seconds, the time before resetting the requests limit, default is 1 second.
• OCD_DTL_REQUESTS_PER_QUOTA_TIME define the number of request to do at maximum for the given time, default is 5 queries.

Please don't exceed the quota marked here for each endpoint

Cli parameters

Parameters common and optional for all commands:

--debug display more information for debugging purposes
-e to change the environment {preprod, prod}, default is prod
-o will set the output file as the API gives it.
-q will quiet the verbosity of the program (but still show errors / warnings)

For information about each command and more, please check the documentation directory
