Simplifying Data and Product Integrations with a Data Abstraction Layer

What this post added

This post introduces the Data Abstraction Layer (DAL) as a key component in simplifying data access and decoupling data consumers from producers. It details the DAL's architecture, request/response flow, and the underlying table resolution process. The DAL addresses the challenges of evolving data models and heterogeneous data sources by providing a unified interface for accessing various data types, exemplified by its application in advertiser reporting. This contributes to the broader goal of managing and accessing data more effectively within Uber's decentralized data ecosystem.
