Description:
Spark SQL is a very effective distributed SQL engine for OLAP and widely adopted in Baidu production for many internal BI projects. However, Baidu has also been facing many challenges for large scale including tuning the shuffle parallelism for thousands of jobs, inefficient execution plan, and handling data skew.nnIn this talk, we will explore Intel and Baidu’s joint efforts to address challenges in large scale and offer an overview of an adaptive execution mode we implemented for Baidu’s B
