Study Notes
Extract, Transform, and Load (ETL) Data Pipeline Pattern
- This pattern focuses on adjusting or transforming data before loading it into BigQuery
- Google Cloud offers multiple services for handling distributed data processing
- Tools like Dataprep and Data Fusion provide visual interfaces for ETL data pipelines
- Dataproc and Dataflow are options for developers preferring open-source frameworks
- Template support streamlines workflows from extraction to transformations
Google Cloud GUI Tools for ETL Pipelines
- Google Cloud provides user-friendly graphical user interfaces (GUIs) for ETL data pipelines
- Tools facilitate ETL tasks without extensive coding
- These tools simplifies complex data transfer, transformation, and loading processes
Batch Data Processing using Dataproc
- Dataproc is a managed service enabling Apache Hadoop and Spark workloads on Google Cloud
- It allows running HDFS data stored on Cloud Storage through Spark jobs
- Output data from these jobs can be stored in various destinations like Cloud Storage, BigQuery, or NoSQL databases like Bigtable
Dataproc Serverless for Spark
- Dataproc Serverless simplifies Spark workload execution by eliminating cluster management
- It provides automatic scaling, cost efficiency, faster deployment, and no resource contention
- Ideal for batch processing interactive notebooks, and Vertex AI pipelines
Streaming Data Processing Options
- Streaming ETL workloads on Google Cloud require continuous data ingestion, processing, and near real-time analytics
- Event data is often ingested through Pub/Sub
- Dataflow (using Apache Beam) processes data in real-time, facilitating transformation and enrichment
- Processed data is loaded into destinations like BigQuery for analytics or Bigtable for NoSQL storage
Bigtable and Data Pipelines
- Bigtable is a suitable destination for streaming data pipelines requiring millisecond-level latency analytics
- It uses a wide-column data model with flexible schemas and efficient indexes
- Row keys are used as indexes for quick data access; this option is ideal for a wide variety of time-series and other types of analytics
Dataflow and Apache Beam
- Dataflow leverages the Apache Beam programming framework for processing batch and stream data
- It provides a unified programming model enabling the use of languages like Java, Python, or Go
- Dataflow seamlessly integrates with Google Cloud services via a pipeline runner, serverless execution, templates, and notebooks
- This simplifies development and provides a streamlined experience
Using Pub/Sub
- Pub/Sub acts as a central hub, receiving and distributing events to various consuming systems
- It is suitable for ingestion of high volumes of event data
- It ensures efficient management of event data through decoupled asynchronous communication
Lab: Dataproc Serverless for Spark to Load BigQuery
- This lab task uses Dataproc Serverless for Spark to load data into BigQuery
- The process involves configuring the environment, downloading lab assets, configuring and executing Spark code, and viewing data in BigQuery
Lab: Creating a Streaming Data Pipeline
- This lab task creates a streaming data pipeline for a real-time dashboard using Dataflow
- Tasks include creating a Dataflow job (using a template), streaming data into BigQuery, monitoring pipeline status in BigQuery, analyzing the data using SQL ,and visualizing key metrics in Looker Studio
Data Fusion
- This is a GUI-based tool for enterprise data integration
- It connects to various data sources, both on-premises and cloud-based
- It enables building data pipelines without coding using a drag-and-drop interface and pre-built transformations
Dataprep
- Dataprep by Trifacta is used for data transformation flows
- It is a serverless, no-code solution that connects to diverse data sources and offers pre-built transformation functions
- It allows users to chain functions into recipes for seamless execution
- It provides scheduling and monitoring capabilities, along with a visual previewing feature, helping users refine data cleaning and preparation tasks
