How to get open/closed workflow list from Java code in Uber Cadence?

I'm working on a project that used Uber Cadence Java Client. How can I get the list of open/closed workflows from the code? I can get it from CLI but not from java code.
Thank you.

WorkflowServiceTChannel cadenceService =
new WorkflowServiceTChannel(ClientOptions.defaultInstance());
ListOpenWorkflowExecutionsRequest request = new ListOpenWorkflowExecutionsRequest();
request.setDomain(DOMAIN);
=request.set...;
ListOpenWorkflowExecutionsResponse resp = cadenceService.ListOpenWorkflowExecutions(request);
ListClosedWorkflowExecutionsRequest request = new ListClosedWorkflowExecutionsRequest();
request.setDomain(DOMAIN);
=request.set...;
ListClosedWorkflowExecutionsResponse resp = cadenceService.ListClosedWorkflowExecutions(request);
// If you have advanced visibility
ListWorkflowExecutionsRequest request = new ListWorkflowExecutionsRequest();
request.setDomain(DOMAIN);
=request.setQuery(...);
ListWorkflowExecutionsResponse resp = cadenceService.ListWorkflowExecutions(request);
See how the cadenceService is used in this sample

AWS Api Gateway JAVA SDK Add Usage Plan to API Key

The following code will create a new API KEY in AWS API Gateway. Just for fun, I also get an existing usage plan called "Basic" with an id of "1234"
For the life of me I can't find out how to take my newly created API Key and add the existing usage plan to it. This can be done manually on the web portal with the "Add to Usage Plan" button but I want to add my new user to a free plan.
BasicAWSCredentials awsCreds = new BasicAWSCredentials(aws_id, aws_key);
apiGateway = AmazonApiGatewayClientBuilder.standard()
.withCredentials(new AWSStaticCredentialsProvider(awsCreds))
.withRegion(Regions.US_EAST_1).build();
CreateApiKeyRequest createApiKeyRequest = new CreateApiKeyRequest();
createApiKeyRequest.setName("awesome company);
createApiKeyRequest.setEnabled(true);
createApiKeyRequest.setCustomerId("someid");
CreateApiKeyResult result = apiGateway.createApiKey(createApiKeyRequest);
GetUsagePlanRequest getUsagePlanRequest = new GetUsagePlanRequest();
getUsagePlanRequest.setUsagePlanId("1234");
GetUsagePlanResult getUsagePlanResult = apiGateway.getUsagePlan(getUsagePlanRequest);
Any AWS SDK experts know how to connect a usage plan to an api key?

Here's the solution to my post - the key type being "API_KEY" isn't documented anywhere, i found it in some random python sample :/ This creates a new user with an api key and adds them to a usage plan with the api gateway java sdk
BasicAWSCredentials awsCreds = new BasicAWSCredentials(aws_id, aws_key);
apiGateway = AmazonApiGatewayClientBuilder.standard()
.withCredentials(new AWSStaticCredentialsProvider(awsCreds))
.withRegion(Regions.US_EAST_1).build();
CreateApiKeyRequest createApiKeyRequest = new CreateApiKeyRequest();
createApiKeyRequest.setName("My awesome new user");
createApiKeyRequest.setEnabled(true);
createApiKeyRequest.setCustomerId(UUID.randomUUID().toString());
CreateApiKeyResult result = apiGateway.createApiKey(createApiKeyRequest);
GetUsagePlanRequest getUsagePlanRequest = new GetUsagePlanRequest();
getUsagePlanRequest.setUsagePlanId(BASIC_USAGE_PLAN_ID);
CreateUsagePlanKeyRequest createUsagePlanKeyRequest = new CreateUsagePlanKeyRequest()
.withUsagePlanId(BASIC_USAGE_PLAN_ID);
createUsagePlanKeyRequest.setKeyId(result.getId());
createUsagePlanKeyRequest.setKeyType("API_KEY");
apiGateway.createUsagePlanKey(createUsagePlanKeyRequest);

This should maybe be a comment instead, but I made an answer for readability (the key type is documented here).
// Client
AmazonApiGateway client = AmazonApiGatewayClientBuilder.standard().withRegion("my region here").build();
// Create new key
CreateApiKeyRequest keyReq = new CreateApiKeyRequest();
keyReq.setName("key name");
keyReq.setDescription("description");
keyReq.setEnabled(true);
CreateApiKeyResult keyRes = client.createApiKey(keyReq);
// Use existing plan
CreateUsagePlanKeyRequest planReq = new CreateUsagePlanKeyRequest();
planReq.setUsagePlanId("my usage plan id");
planReq.setKeyId(keyRes.getId()); // id from new key
planReq.setKeyType("API_KEY");
// add key to plan
client.createUsagePlanKey(planReq);
Note, this example is without a try-catch block

BigQuery - how to register a UDF from the Java Client

I see from the docs that UserDefinedFunctionResource exists, but I can't find the right call to hook it up to a query job. I'd like to add a resource to gs and register it before running a query using the Java API.
Thanks in advance.

You should add UserDefinedFunctionResource items to your JobConfigurationQuery object. Something like this:
Job content = new Job();
JobConfiguration cfg = new JobConfiguration();
JobConfigurationQuery jobConfigurationQuery = new JobConfigurationQuery();
UserDefinedFunctionResource userDefinedFunctionResource = new UserDefinedFunctionResource();
userDefinedFunctionResource.setResourceUri("gs://mybucket/udf.js");
jobConfigurationQuery.setUserDefinedFunctionResources(Lists.newArrayList(
userDefinedFunctionResource
));
cfg.setQuery(jobConfigurationQuery);
content.setConfiguration(cfg);
Bigquery.Jobs.Insert request = bigqueryService.jobs().insert(projectId, content);
Job response = request.execute();

AWS import vmdk java

I am trying to import the vmdk to AWS EC2, but there seems to be no good java API documentation.
I have come across below flow, which should work,
DiskImageDetail id = new DiskImageDetail();
id.setFormat(DiskImageFormat.VMDK);
// id.setImportManifestUrl(importManifestUrl)
// TODO: set to 10GB e.g.
id.setBytes(80000000000L);
VolumeDetail volume = new VolumeDetail();
volume.setSize(80000000000L);
DiskImage i = new DiskImage();
i.setImage(id);
i.setVolume(volume);
i.setDescription("disk image");
List<DiskImage> listImages = new ArrayList<DiskImage>();
listImages.add(i);
ImportInstanceLaunchSpecification ls = new ImportInstanceLaunchSpecification();
ImportInstanceRequest ir = new ImportInstanceRequest();
ir.setDescription("Test");
ir.setDiskImages(listImages);
ir.setRequestCredentials(Connection.getAWSCredentials());
// ir.setGeneralProgressListener()
ir.setLaunchSpecification(ls);
// Some code to set
ImportVolumeRequest ivr = new ImportVolumeRequest();
//ivr.setSomeData();
AmazonEC2 ec2 = // set some connection
ec2.importInstance(ir);
ec2.importVolume(ivr);
But I am not sure about what values to pass, there's no sample code as well !
It can be done with the cmdlets but with Java I don't see anything hopeful.
Appreciate any help on this.
Thanks in advance

Overriding authentication behavior in jclouds

I'm looking to leverage RackSpace's CloudFiles platform for large object storage (word docs, images, etc). Following some of their guides, I found a useful code snippet, that looks like it should work, but doesn't in my case.
Iterable<Module> modules = ImmutableSet.<Module> of(
new Log4JLoggingModule());
Properties properties = new Properties();
properties.setProperty(LocationConstants.PROPERTY_ZONE, ZONE);
properties.setProperty(LocationConstants.PROPERTY_REGION, "ORD");
CloudFilesClient cloudFilesClient = ContextBuilder.newBuilder(PROVIDER)
.credentials(username, apiKey)
.overrides(properties)
.modules(modules)
.buildApi(CloudFilesClient.class);
The problem is that when this code executes, it tries to log me in the IAD (Virginia) instance of CloudFiles. My organization's goal is to use the ORD (Chicago) instance as primary to be colocated with our cloud and use DFW as a back up environment. The login response results in the IAD instance coming back first, so I'm assuming JClouds is using that. Browsing around, it looks like the ZONE/REGION attributes are ignored for CloudFiles. I was wondering if there is any way to override the code that comes back for authentication to loop through the returned providers and choose which one to login to.
Update:
The accepted answer is mostly good, with some more info available in this snippet:
RestContext<CommonSwiftClient, CommonSwiftAsyncClient> swift = cloudFilesClient.unwrap();
CommonSwiftClient client = swift.getApi();
SwiftObject object = client.newSwiftObject();
object.getInfo().setName(FILENAME + SUFFIX);
object.setPayload("This is my payload."); //input stream.
String id = client.putObject(CONTAINER, object);
System.out.println(id);
SwiftObject obj2 = client.getObject(CONTAINER,FILENAME + SUFFIX);
System.out.println(obj2.getPayload());

We are working on the next version of jclouds (1.7.1) that should include multi-region support for Rackspace Cloud Files and OpenStack Swift. In the meantime you might be able to use this code as a workaround.
private void uploadToRackspaceRegion() {
Iterable<Module> modules = ImmutableSet.<Module> of(new Log4JLoggingModule());
String provider = "swift-keystone"; //Region selection is limited to swift-keystone provider
String identity = "username";
String credential = "password";
String endpoint = "https://identity.api.rackspacecloud.com/v2.0/";
String region = "ORD";
Properties overrides = new Properties();
overrides.setProperty(LocationConstants.PROPERTY_REGION, region);
overrides.setProperty(Constants.PROPERTY_API_VERSION, "2");
BlobStoreContext context = ContextBuilder.newBuilder(provider)
.endpoint(endpoint)
.credentials(identity, credential)
.modules(modules)
.overrides(overrides)
.buildView(BlobStoreContext.class);
RestContext<CommonSwiftClient, CommonSwiftAsyncClient> swift = context.unwrap();
CommonSwiftClient client = swift.getApi();
SwiftObject uploadObject = client.newSwiftObject();
uploadObject.getInfo().setName("test.txt");
uploadObject.setPayload("This is my payload."); //input stream.
String eTag = client.putObject("jclouds", uploadObject);
System.out.println("eTag = " + eTag);
SwiftObject downloadObject = client.getObject("jclouds", "test.txt");
System.out.println("downloadObject = " + downloadObject.getPayload());
context.close();
}
Use swift as you would Cloud Files. Keep in mind that if you need to use Cloud Files CDN stuff, the above won't work for that. Also, know that this way of doing things will eventually be deprecated.
