What are some common data warehouse challenges?


Common data warehouses can have slow query performance especially when all the data operations happen on the same clusters.  Also, many data warehouses have closed architectures which limits choices and drives up egress fees to use the data. Additionally,  data warehouses aren’t built to handle real-time analytics which usually require the ability to handle small writes. Lastly, data warehouses often duplicate the storage of data which balloons costs and hinders the ability to have a single source of truth.
