We are currently using Google's Cloud Dataflow SDK (1.6.0) to run dataflow jobs in GCP, however, we are considering moving to the Apache Beam SDK (0.1.0). We will still be running our jobs in GCP using the dataflow service. Has anyone gone through this transition and have advice? Are there any compatibility issues here and is this move encouraged by GCP?
Formally Beam is not yet supported on Dataflow (although that is certainly what we are working towards). We recommend staying with the Dataflow SDK, especially if SLA or support are important to you. that said, our tests show that Beam runs on Dataflow, and although that may break at any time, you are certainly welcome to attempt at your own risk.
Update:
The Dataflow SDKs are now based on Beam as of the release of Dataflow SDK 2.0 (https://cloud.google.com/dataflow/release-notes/release-notes-java-2). Both Beam and the Dataflow SDKs are currently supported on Cloud Dataflow.
You can run Beam SDK pipelines on Dataflow now. See:
https://beam.apache.org/documentation/runners/dataflow/
You'll need to add a dependency to pom.xml, and probably a few command-line options as explained on that page.

Tried to implement the Cloud data-flow task, loading data from PostgreSQL database table to Google Cloud Bigquery table help of below URL document. When executing data-flow job got issue. Refer the screen shot [1].

Google Cloud Dataflow supports 2.x version of SDK. Since this code is with version 1.x so got this generic issue when run the dataflow pipeline in Google Cloud. After migrate it to 2.x version able to run the code successfully.
We are planning to config CI for our mobile apps (both Android and iOS). I've tried to use Device Farm with our Java and TestNG scrips and it works well. However, I have no idea how to use your device cloud with our current GoCD to implement CI/CD for mobile development. I noticed Device Farm have plugin for Jenkins but not GoCD.
Could you guys please consult me in this case? Thanks alot.
AWS Device Farm engineer here. We don't have any plans (as of mid-2017) to develop a GoCD plugin. However, the service API is documented and publicly available and you can use it and the Jenkins implementation as a reference to build your own integration.
It's really confusing that every Google document for dataflow is saying that it's based on Apache Beam now and directs me to Beam website. Also, if I looked for github project, I would see the google dataflow project is empty and just all goes to apache beam repo. Say now I need to create a pipeline, from what I read from Apache Beam, I would do : from apache_beam.options.pipeline_options However, if I go with google-cloud-dataflow, I'll have error: no module named 'options' , turns out I should use from apache_beam.utils.pipeline_options. So, looks like google-cloud-dataflow is with an older beam version and is going to be deprecated?
Which one should I pick do develop my dataflow pipeline?
Ended up finding answer in Google Dataflow Release Notes
The Cloud Dataflow SDK distribution contains a subset of the Apache Beam ecosystem. This subset includes the necessary components to define your pipeline and execute it locally and on the Cloud Dataflow service, such as:
The core SDK
DirectRunner and DataflowRunner
I/O components for other Google Cloud Platform services
The Cloud Dataflow SDK distribution does not include other Beam components, such as:
Runners for other distributed processing engines
I/O components for non-Cloud Platform services
Version 2.0.0 is based on a subset of Apache Beam 2.0.0
Yes, I've had this issue recently when testing outside of GCP. This link help to determine what you need when it comes to apache-beam. If you run the below you will have no GCP components.
$ pip install apache-beam
If you run this however you will have all the cloud components.
$ pip install apache-beam[gcp]
As an aside, I use the Anaconda distribution for almost all of my python coding and packages management. As of 7/20/17 you cannot use the anaconda repos to install the necessary GCP components. Hoping to work with the Continuum folks to have this resolved not just for Apache Beam but also for Tensorflow.
I have created Pipeline in Python using Apache Beam SDK, and Dataflow jobs are running perfectly from command-line.
Now, I'd like to run those jobs from UI. For that i have to create template file for my job. I found steps to create template in Java using maven.
But how do I do it using the Python SDK?
Templates are available for creation in the Dataflow Python SDK since April of 2017. Here is the documentation.
To run a template, no SDK is needed (which is the main problem templates try to solve), so you can run them from the UI, REST API, or CL and here is how.
I want to integrate the web artifacts part of my application with brunch.io.Could not find some descent google search for the same.
Can anybody help out?
Use Maven-exec to run a shell script that runs your brunch build command.
Reviewing this article about maven/grunt integration will probably also be helpful, as the underlying concepts for running a Node.js tool from maven are basically the same.
