Variety of requirements to Data Warehouse. How to talk to the customer and cover all important issues

In the talk, we will examine different categories of requirements for the Data Warehouse and how to take them into account in implementation. As a result, you will have a list of questions for the customer that would be good to clear up before you start building a new DWH. For an already existing DWH, it can be used to isolate problem query patterns for which it is worth dedicating separate subsystems.

Talk is not bound to a specific technology. Examples will use Impala/Hive, Clickhouse, ScyllaDB/Cassandra, PostgreSQL.
