Issue DM-4919: Test performance of vertical-partition joins in mysql
We are planning to vertically partition some tables (for example Object). We should make sure such joins across say 5, 10 or 20 tables are not a problem for mysql from performance standpoint. The testing involves creating a wide table (say 200 columns) and testing a speed of full scan, then slicing that table vertically into different number of columns and using join to assemble the pieces together.
