I want to assign specific environment variables but I am getting a bit confused with the documentation. > • `MELTANO_EXTRACT_SETTING_NAME`: one environment variable for each of the extractor's settings and extras, e.g.

MELTANO_EXTRACT_PRIVATE_TOKEN

for the

private_token

setting, and

MELTANO_EXTRACT__LOAD_SCHEMA

for the

load_schema

extra > • `SETTING_ENV`: all of the extractor's regular configuration environment variables, as listed by

meltano config <plugin> list

, e.g.

TAP_GITLAB_API_URL

for the

api_url

setting 1. When do you use one underscore before the setting name and when do you use two? a. MELTANO_EXTRACT_PRIVATE_TOKEN b. MELTANO_EXTRACT__LOAD_SCHEMA 2. Is MELTANO_EXTRACT and TAP_GITLAB interchangeable? For example, will MELTANO_EXTRACT_API_URL have the same impact on the run as TAP_GITLAB_API_URL?

When do you use one underscore before the setting name and when do you use two?

Only extras should have an double underscore: https://docs.meltano.com/concepts/plugins/#extras

Is MELTANO_EXTRACT and TAP_GITLAB interchangeable? For example, will MELTANO_EXTRACT_API_URL have the same impact on the run as TAP_GITLAB_API_URL?

Whenever you're referring to

tap-gitlab

in config/invoke/el/run, yes.

The first answer makes sense but still a little confused on the second point. Here is an example:

TAP_GITLAB_API_URL='example' meltano run tap-gitlab target-jsonl

MELTANO_EXTRACT_API_URL='example' meltano run tap-gitlab target-jsonl

TAP_GITLAB___CATALOG='example' meltano run tap-gitlab target-jsonl

MELTANO_EXTRACT__CATALOG='example' meltano run tap-gitlab target-jsonl

Will both of those commands set the exact same setting during runtime?
