AWS providers for JWorkflow

• Provides support to persist long running workflows for JWorkflow backed by Amazon DynamoDB
• Provides support to run multi-node clusters of JWorkflow, by providing a distributed lock manager (via DynamoDB) and/or a shared work queue (via Simple Queue Service).

Installing

Using Maven

<dependencies>
    <dependency>
        <groupId>net.jworkflow</groupId>
        <artifactId>jworkflow.providers.aws</artifactId>

}

Usage for Persistence

import software.amazon.awssdk.regions.Region;
import net.jworkflow.providers.aws.DynamoDBPersistenceProvider;
...
...

WorkflowModule module = new WorkflowModule();

module.usePersistence(new DynamoDBPersistenceProvider(Region.US_WEST_1, "table-prefix"));

module.build();
WorkflowHost host = module.getHost();

Usage for Shared Work Queue

import software.amazon.awssdk.regions.Region;
import net.jworkflow.providers.aws.SQSProvider;
...
...

WorkflowModule module = new WorkflowModule();

module.useQueue(new SQSProvider(Region.US_WEST_1));

module.build();
WorkflowHost host = module.getHost();

Usage for Distributed Lock Manager

import software.amazon.awssdk.regions.Region;
import net.jworkflow.providers.aws.DynamoDBLockProvider;
...
...

WorkflowModule module = new WorkflowModule();

module.useDistibutedLock(new DynamoDBLockProvider(Region.US_WEST_1, "jworkflowLockTable")); //DynamoDB table name of your choice

module.build();
WorkflowHost host = module.getHost();
