beam-sandbox

How To Start

1. Enable some of the GCP APIs (dataflow api, json api, logging api, biq query api, storage api, datastore api) from GCP console UI
2. Establish an environment for beam
   • create a conda conda create -n beam-sandbox environment,
   • activate w/ conda activate beam-sandbox and
   • install pip install apache-beam[gcp, test] for GCP & Test additions
3. Test environment w/
   • python -m apache_beam.examples.wordcount --output beam/text,
   • Then, cat beam/t* to see words and counts.
4. Create a bucket for dataflow on GCP Storage, right after creating a GCP Project !
   • Edit ./run-count-dataflow.sh file and change w/ your ${PROJECT_ID}
   • Create a bucket named beam-pipelines-123
   • Under this folder create folders for every beam file such as line-count
     • then, staging and temp folders such as line-count\staging and
     • line-count\temp folders
5. Create a dataset bucket gs://spark-dataset-1 on GCP Storage, and upload dataset folder into it. Public bucket level is much better.
6. export GOOGLE_APPLICATION_CREDENTIALS=PATH_OF_SERVICE_ACCOUNT.json

How To Run

1. to run
   • python line-count.py on your local (uses DirectRunner), or
   • Run on your local or GCP shell/Instance ./line-count-dataflow.sh (uses DataFlowRunner)
2. Look Dataflow UI on GCP console and dataflow jobs running.
3. Check logs
