We have a number of partitioned tables in a couple of existing data warehouses. We are working on the design for a new warehouse and need to decide which tables should be partitioned.
For you folks that have partitioned tables, how do you decide which tables to be partition? Some tables with very large row counts are obvious candidates. If you go off of row counts solely, what is the cut-off point for where you should start partitioning? Is there a rule-of-thumb? I'm having difficulty with the not-as-huge, not-as-obvious candidates. What other criteria do you use besides row-count? Perhaps archival requirements? I guess it would depend on what you are using the partitioning to achieve. Partition exclusion for read performance improvement or for culling off old data, etc. Any shared insights for where to draw the line on partitioning candidates would be greatly appreciated.
