Daniel Abadi

Daniel Abadi is the Darnell-Kanal Professor of Computer Science at University of Maryland, College Park. His primary area of research is database systems, with contributions to stream databases, distributed databases, graph databases, and column-store databases. He helped create C-Store, a column-oriented database, and HadoopDB, a hybrid of relational databases and Hadoop. Both database systems were commercialized by companies.

Abadi was the first to describe the PACELC theorem in a 2010 blog post. PACELC, a response to the CAP theorem, was proved formally in 2018 in a SIGACT News article. Provided by Wikipedia
