java - Running Google Dataflow with PubsubIO source for testing -


i'm creating data-processing application using google cloud dataflow - going stream data pubsub bigquery.

i'm bewildered infrastructure. created application prototype , can run locally, using files (with textio) source , destination.

however if change source pubsubio.read.subscription(...) fail "java.lang.illegalstateexception: no evaluator registered pubsubio.read" (i not surprised since see no methods pass authentication anyway).

but how supposed run this? should create virtual machine in google cloud engine , deploy stuff there, or supposed describe job somehow , submit dataflow api (without caring of explicit vm-s?)

could please point me kind of step-by-step instruction on topic - or rather explain workflow shortly. i'm sorry question silly.

you need run pipeline on google cloud infrastructure in order access pubsub, see: https://cloud.google.com/dataflow/pipelines/specifying-exec-params#cloudexecution

from page:

// create , set pipelineoptions. dataflowpipelineoptions options = pipelineoptionsfactory.as(dataflowpipelineoptions.class);  // cloud execution, set cloud platform project, staging location, // , specify dataflowpipelinerunner or blockingdataflowpipelinerunner. options.setproject("my-project-id"); options.setstaginglocation("gs://my-bucket/binaries"); options.setrunner(dataflowpipelinerunner.class);  // create pipeline specified options. pipeline p = pipeline.create(options);  // specify pipeline reads, transforms, , writes. ...  // run pipeline. p.run();
