   > One more note, in utils.py we're also using some db methods like 
`DagRun.fetch_task_instances` 
[here](https://github.com/apache/airflow/blob/cf80ae19840f1d03e16323e7bca819550633db97/providers/openlineage/src/airflow/providers/openlineage/utils/utils.py#L988),
 but we only call it on scheduler. We're also going to add another call to db 
[here](https://github.com/apache/airflow/pull/59521/changes#diff-090bdefe8e3de4ab44c24490d0b0df9ff2f9445d2d42126e0ce3476908b804d5R1075)
 for asset triggered dagruns, also performed only on scheduler. Not sure how 
this relates to treating sqlalchemy as optional.
   
   Not yet. This will come later when we will split (some) providers into two 
types of providers (maybe they won't be named like that) - we've been disussing 
it but deferred decision on that to after we complete task isolation and 
separated core and task-sdk. We iwll have to separate some distributions in two:
   
   * executors/ui plugins/scheduler listeners and plugins (installable with 
airflow-core)
   * Hooks/Operators/macro plugins etc. (installable with task-sdk)
   
   This falls in the same part - part of the current openlineage provider 
should be a distribution installed with "task-sdk" and part should be another 
distribution installed with "airflow-core".
   
   Later we can even split "airflow-ui" as separate distribution and have 3 
types of "providers"
