Building Robust ETL Pipelines with Apache Spark - Xiao Li
Показать описание
Stable and robust ETL pipelines are a critical component of the data infrastructure of modern enterprises. ETL pipelines ingest data from a variety of sources and must handle incorrect, incomplete or inconsistent records and produce curated, consistent data for consumption by downstream applications.
In this talk, we'll take a deep dive into the technical details of how Apache Spark "reads" data and discuss how Spark 2.2's flexible APIs; support for a wide variety of datasources; state of art Tungsten execution engine; and the ability to provide diagnostic feedback to users, making it a robust framework for building end-to-end ETL pipelines.
Overview:
1) What’s an ETL Pipeline?
2) Using Spark SQL for ETL
- Extract: Dealing with Dirty Data (Bad Records or Files)
- Extract: Multi-line JSON/CSV Support
- Transformation: High-order functions in SQL
- Load: Unified write paths and interfaces
3) New Features in Spark 2.3
- Performance (Data Source API v2, Python UDF)
