Engineering Lakehouses with Open Table Formats
By :
This chapter provided an in-depth exploration of Apache Hudi, an open source data lake framework that introduces transactional capabilities to data lakes. We began by understanding Hudi’s architecture, including its metadata and data layers, which help ensure efficient storage, schema evolution, and incremental data processing.
We then explored Hudi’s core capabilities, such as row-level updates and deletes, time travel, and ACID transactions, making it an ideal solution for managing large-scale datasets in both batch and streaming workloads. Through hands-on exercises, we demonstrated how to perform various data operations using Apache Spark and Flink, including writing, reading, and catalog synchronization with Hive Metastore and AWS Glue.
Additionally, we covered key table services in Hudi, such as compaction, clustering, and data cleaning, which optimize storage efficiency and query performance. The chapter also introduced Hudi’s rollback mechanisms...
