SIMPLIFYING DATA AND PRODUCT INTEGRATIONS WITH A DATA ABSTRACTION LAYER

Summary from the TLDR Data newsletter

Uber's Data Abstraction Layer decouples product integrations from changing physical tables, schemas, and backends. A logical table plus FetchData API can resolve queries across real-time and daily tables, OLAP stores, Docstore, and Hive, then roll up metrics by requested dimensions. Advertiser reporting delivery fell from weeks to under two days.
