Amundsen is an open-source data discovery and metadata platform which is part of LF AI & Data foundation. In this talk, we will deep dive into Amundsen’s architecture and how we integrate Amundsen with Presto to power the data preview and data exploration.
In this talk, Walaa describes how LinkedIn extended its Presto Hive Catalog with a smart logical abstraction layer that is capable of reasoning about logical views with UDFs by using two core components, Coral and Transport UDFs. Coral is a view virtualization library, powered by Apache Calcite, that represents views using their logical query plans. Walaa shows how LinkedIn leverages Coral abstractions to decouple view expression language from the execution engine, and hence execute non-Presto-SQL views inside Presto, and achieve on-the-fly query rewrite for data governance and query optimization.
