As you can imagine indexes, called memory optimized indexes are different for these types of tables, so let’s see just how different that are from regular tables. Before we dive into this subject it is VERY important to note the biggest differences. First, ALL memory optimized indexes MUST be created when the table is created or migrated. You cannot add indexes in an existing table without dropping and recreating the table.… Continue Readinghttps://i1.wp.com/sqlespresso.com/wp-content/uploads/2020/01/memidx1.png?resize=700%2C388&ssl=1
