Usage

revoscalepy.rx_get_job_status(job_info: revoscalepy.computecontext.RxRemoteJob.RxRemoteJob) -> revoscalepy.computecontext.RxJob.RxRemoteJobStatus

Description

Obtain distributed computing processing status for the specified job.

Arguments

job_info

A job object as returned by rx_exec or a revoscalepy analysis function, if available.

Returns

A RxRemoteJobStatus enumeration value that designates the status of the remote job

Example

from revoscalepy import RxInSqlServer
from revoscalepy import rx_exec
from revoscalepy import rx_get_job_status
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)

# Poll initial status
status = rx_get_job_status(job)

print(status)

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

# Poll final status
status = rx_get_job_status(job)

print(status)
