Class MultiLangDaemon

java.lang.Object

com.amazonaws.services.kinesis.multilang.MultiLangDaemon

All Implemented Interfaces:

java.util.concurrent.Callable<java.lang.Integer>

public class MultiLangDaemon
extends java.lang.Object
implements java.util.concurrent.Callable<java.lang.Integer>

Main app that launches the worker that runs the multi-language record processor. Requires a properties file containing configuration for this daemon and the KCL. A properties file should at minimum define these properties:

 # The script that abides by the multi-language protocol. This script will
 # be executed by the MultiLangDaemon, which will communicate with this script
 # over STDIN and STDOUT according to the multi-language protocol.
 executableName = sampleapp.py
 
 # The name of an Amazon Kinesis stream to process.
 streamName = words
 
 # Used by the KCL as the name of this application. Will be used as the name
 # of a Amazon DynamoDB table which will store the lease and checkpoint
 # information for workers with this application name.
 applicationName = PythonKCLSample
 
 # Users can change the credentials provider the KCL will use to retrieve credentials.
 # The DefaultAWSCredentialsProviderChain checks several other providers, which is
 # described here:
 # http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html
 AWSCredentialsProvider = DefaultAWSCredentialsProviderChain
