How do I get job definition from
instance.get_run_records
run record that would fit into
execute_job
method?

To execute a job using the
execute_job
method, you typically need a reconstructable job definition. The
instance.get_run_records
method returns a list of
RunRecord
objects, which contain information about past runs, but not the job definitions themselves. However, if you have a
RunRecord
object from
instance.get_run_records
, you can extract the
run_id
from it. With the
run_id
, you can potentially reconstruct the job if you have the original code that defines the job. Here's a step-by-step approach based on the documentation: 1. Use
instance.get_run_records
to retrieve the run records you're interested in. 2. Extract the
run_id
from the
RunRecord
object. 3. If you know the original job definition (the Python function or module where the job is defined), you can use
reconstructable
to create a reconstructable job. 4. Pass the reconstructable job to
execute_job
along with the necessary parameters such as
instance
,
run_config
,
tags
, etc. Here's an example of how you might use the
run_id
to reexecute a job, assuming you have the original job definition:
Copy code
python from dagster import execute_job, reconstructable, DagsterInstance, ReexecutionOptions  # Assuming you have a function that defines your job def define_job():     ...  # Get the Dagster instance instance = DagsterInstance.get()  # Retrieve run records (you would add your own filters here) run_records = instance.get_run_records()  # Extract the run_id from the RunRecord you're interested in run_id = run_records[0].run_id  # Create a reconstructable job reconstructable_job = reconstructable(define_job)  # Define reexecution options if needed reexecution_options = ReexecutionOptions.from_failure(run_id=run_id, instance)  # Execute the job execute_job(reconstructable_job, instance, reexecution_options=reexecution_options)
Please note that this example assumes you have a function
define_job
that can be used to reconstruct the job. If you don't have access to the original job definition, you won't be able to reconstruct the job and execute it in this manner.
