Deep Dive Into Hudi’s Indexing Subsystem (Part 1 of 2)

For decades, databases have relied on indexes—specialized data structures—to dramatically improve read and write performance by quickly locating specific records.

Every Hudi table contains a self-managed metadata table that functions as an indexing subsystem, enabling efficient data skipping and fast record lookups across a wide range of read and write scenarios.
