Usage

revoscalepy.rx_get_job_output(job_info: revoscalepy.computecontext.RxRemoteJob.RxRemoteJob) -> str

Description

During a job run, the state of the output is non-deterministic (that is, it may or may not be on disk, and what is on disk at any given point in time may not reflect the actual completion state of a job).

If auto_cleanup has been set to True on the distributed computing job’s compute context, the console output will not persist after the job completes.

Unlike rx_get_job_results, this function does not remove any job information upon retrieval.

Arguments

job_info

The distributed computing job for which to retrieve the job output

Returns

str that contains the console output for the nodes participating in the distributed computing job

Example

from revoscalepy import RxInSqlServer
from revoscalepy import rx_exec
from revoscalepy import rx_get_job_output
from revoscalepy import rx_wait_for_job

connection_string = 'Driver=SQL Server;Server=.;Database=RevoTestDb;Trusted_Connection=True;'

# Setting wait to False allows the job to be run asynchronously
# Setting console_output to True allows us to get the console output of the distributed computing job
compute_context = RxInSqlServer(connection_string=connection_string,
                                num_tasks=1,
                                console_output=True,
                                wait=False)

def hello_from_sql():
    import time
    print('Hello from SQL server')
    time.sleep(3)
    return 'We just ran Python code asynchronously on a SQL server!'

job = rx_exec(function=hello_from_sql, compute_context=compute_context)

# Wait for the job to finish or fail whatever the case may be
rx_wait_for_job(job)

# Print out what our code printed on sql
output = rx_get_job_output(job)
print(output)
