kandi X-RAY | jobpipe Summary

jobpipe is a Java library typically used in Automation, BPM applications. jobpipe has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub, Maven.

Java workflow scheduler for pipelines of long-running batch processes, inspired by Spotify Luigi. The purpose of jobpipe is to execute certain tasks at regular time ranges and allow expressing dependencies between tasks as a sequence of continuous executions in time. These tasks can be anything, like Hadoop/Spark jobs, log data processing, data indexing or time series downsampling. Unlike other workflow schedulers like Azkaban and Oozie, Jobpipe is a minimal library with zero dependencies where everything is expressed in code, no XML. Jobpipe tries hard to be unopinionated on how users should build their applications with regards to logging, configuration, monitoring, dependency injection, persistence, security, thread execution etc. Most of these concerns can be implemented by users as they see fit. Download the latest jobpipe release. Abstract Pipeline of Task execution expressed in code. This pipeline can be executed using the command line. The execution of this schedule may yield the following order of execution at exactly 2016-01-14T10:00. Tasks are scheduled immediately if the scheduled date have passed. Task execution is stalled until dependent tasks have valid output. Task 1, 4, 10, 12 may start in parallel. Tasks can have different time ranges. Executing this schedule for 2016-01-10 will yield the following task executions. Since the date have passed, the 'hourly' Task1 tasks may run in parallel and 'daily' Task2 afterwards. A target time range can be sepecified as follows. Tasks accepts arguments that can be parsed with a library like joptsimple. Task execution parallelism can be controlled globally or individually using Scheduler. Observers can be used to implement things like logging, monitoring, persistent history etc. Observers may also reject task execution. The command line jar provides a way for triggering a schedule at a certain time range, like 2016-01, 2013-W12, 2016-10-11 or 2013-12-01T12. Users can also choose to execute only single task through the -task option. Tasks are provided through user built jar files either in the /lib directory of the same directory as the command line jar and/or through the system property -Djobpipe.cp. The following command run task 'task1' of the Pipeline class implementation that matches the regexp SparkPipeline and loads all files in the $SPARK_HOME/lib directory onto classpath (non-recursive). Example of how to run Apache Spark pipelines are found in the SparkPipeline test.

            Answered 2022-Feb-25 at 11:07

            I don't think this is Docker related. Maybe your build process copies files?

            "The deployment contains definitions with the same key 'ct-camunda' (id attribute), this is not allowed" Check if you have packaged multiple .bpmn files into your deployment. Maybe you accidentally copied the model file in an additional classpath location. You seem to have two deployments with the same id. (This is not about the filename, but the technical id used inside the XML)

            If you are using auto deployment in Spring Boot, you do not have to declare anything in the processes.xml. Use this only in combination with @EnableProcessApplication (or do not use both)

            Answered 2022-Feb-08 at 18:16

            You want the play_audio function to be called every 60/bpm seconds, but the function call itself takes time: you need to read the file, open the stream, play the file (who knows how long it is) and close the stream. So that adds to the time from one click to the next.

            To fix this problem, you could try subtracting the time it takes to run the play_audio function from the time you sleep. You could also experiment with running play_audio on a separate thread.

            My skills with Ethereum are still not sharp enough to give you a proper answer, but I hope you get some guidance.

            The error states that you are trying to transfer by a party A certain quantity in the name of another party B, to a third one C, but the amount you are trying to transfer, using transferFrom, is greater than the one party B approved party A to send.

            You can check the actual allowance between to parties using the method with the same name of your contract.

            Please, consider review this integration test from the web3j library in Github. It is different than yours but I think it could be helpful.

            Especially, it states that the actual transferFrom operation should be performed by the beneficiary of the allowance. Please, see the relevant code:

Dictionary is not an array, you should use Add() method, like this: ret.Add(timings, notes_enc[name]);
