Would you like a course on Performance And Tuning your DV? If so, which platforms (tell us in your REPLY to this post). We can offer Performance And Tuning for: Oracle Enterprise, SQLServer (including Big Data Edition), Teradata, and Hive/Spark SQL execution engine.
The idea would be to cover: Partitioning, Indexing, Partition Management. Should this be On-Line? or In Person (specific to your environment??)
Please don't ask for SnowflakeDB - as there really isn't much you can do (if anything) to improve performance there except scale the servers.
