Symptoms

Assume that you use a distributed partitioned view on clustered columnstore index (CCI) tables in Microsoft SQL Server 2014. And there are some loads and queries on the same distributed partitioned view. In this situation, the loads or queries may freeze because of the distributed deadlocks that occur between the loads and queries on the CCI tables.
