Create a One-Time Cron

The Cron component is used to schedule the submission of a job to the job Pool. Using the following SDK, you will be able to create a cron that will schedule a job submission only once.

Ensure the following packages have been imported:

    

        
copy
        

            

        
    
    

         import com.zc.component.jobscheduling.beans.cron.ZCCronDetails;
import com.zc.component.jobscheduling.beans.cron.ZCCronBuilder;
import com.zc.component.jobscheduling.beans.job.ZCJobBuilder;
import com.zc.component.jobscheduling.beans.job.ZCJobMetaDetail;
import org.json.simple.JSONObject;

    

    

        
copy
        

            

        
    
    

         // generate function job meta
ZCJobMetaDetail jobMeta = ZCJobBuilder.functionJobBuilder() // get function job builder
    .setJobConfig(2, 15 * 60 l) // set job config - job retries => 2 retries in 15 mins (optional)
    .setJobpoolName("functions_jobpool") // set the name of the function jobpool (optional) (either jobpoolId or jobpoolName is mandatory)
    // .setJobpoolId(1234567890L) // set the Id of the function jobpool (optional) (either jobpoolId or jobpoolName is mandatory)
    .setTargetName("target_function") // set target function's name (optional) (either TargetName or TargetId is mandatory)
    // .setTargetId(1234567890L) // set the target function's Id (optional) (either TargetName or TargetId is mandatory)
    .setParams(new JSONObject() {
        {
            put("arg1", "job");
            put("arg2", "test");
        }
    }) // set params to be passed to target function (optional)
    .setJobName("job_name") // set job name
    .build(); // build job meta

// generate cron details
ZCCronDetails oneTimeCronDetails = ZCCronBuilder.zcOneTimeCronBuilder() // get one time cron builder
    .setCronStatus(true) // set cron as enabled
    .cronConfig((System.currentTimeMillis() / 1000) + (60 * 60), "America/Los_Angeles") // set the execution time as UNIX timestamp in seconds
    .setJobMeta(jobMeta) // set job meta (modify based on the job)
    .setCronName("one_time_cron") // set cron name (unique)
    .setCronDescription("one_time_cron") // set corn description (optional)
    .build(); // build cron details

// create one time cron
ZCCronDetails oneTimeCron = jobScheduling.cron.createCron(oneTimeCronDetails);
