Hudi is a top-level Apache open-source project and community that is breaking the boundaries of what is possible on a data lake. This talk unveils the essence of Apache Hudi 1.0, a pivotal version that will encapsulate a ground-up reimagination of Hudi's transactional database layer while staying true to its foundational principles. Diving deep, we'll explore:

1. State of the project: How Hudi today is a versatile data lake platform, enabling automated, near real-time data ingestion and incremental processing, integrated seamlessly with powerful frameworks such as Apache Spark, Flink, and Kafka Connect.
2. Hudi 1.0: An insightful look into how Hudi is architecting the foundational blocks of its database kernel. From implementing non-blocking concurrency control, and faster access methods with improved indexing and metadata, to leveraging an LSM tree-style timeline for infinite time travel – Hudi is redesigning every facet to optimize data lakes at scale.
3. The road ahead: Understanding the potential of transforming Hudi's core into a universal database experience for the lake, diving into deep query engine integrations, employing a hybrid server architecture, and expanding capabilities for complex data types, including images, videos, and formats conducive to ML/AI.

As Hudi 1.0 prepares to set a new benchmark in the world of streaming data lakes, this talk invites feedback, ideas, and collaborations to augment its scope and deliver unparalleled value to the user community. Join us to be part of this transformational journey!
