using_apache_spark_to_optimise_data_processing's Introduction

Augmenting image processing task in TensorFlow with Apache Spark

The project presents a means of augementing several image process steps using Apache Spark. The projecct considers:

  • The optimium number of spark partitions for the workload.
  • The best compute configuration for the Dataproc cluster to achieve the fastsest results of the task.
  • Analysis of key varriable and how they impact resulting outputs 'batch size' 'dataset_size' 'program repetitions', and experiment repitions, impact the 'images per second' read speed.

This project uses GCP services Dataproc and Colab.
