> If what you're referring to multi-table joins (a left hand table joined with one or multiple right hand tables), all right hand tables share the same properties. I think it would be interesting to write a few benchmarks where the right hand tables have a bit more variation amongst themselves. I think I was mostly curious about differences in density between the left table and the right table(s). For example, a dense left table and a sparse right table or a sparse left table and a dense right table. The left table roughly defines the keyframes so I would expect the density of the left table to be more significant to performance than the density of the right table. -- This is an automated message from the Apache Git Service.
