I am currently exploring the possibility of implementing a datawarehouse with corresponding BI tools with Clickhouse. Typically, dimensional data modeling leads to many joins in queries, which should be avoided in order to optimize performance. Clickhouse recommends using dictionaries instead. So far, so good. Now I wonder, how the BI client application will work with these dictionaries. Obviously, this question depends on the interface that is used for communication between the client and clickhouse (especially for making analytical queries). Since clickhouse-specific dictionaries are not supported by JDCB/ODBC, these options are out of question - am I right? Which interface is the best option for this purpose?
