Virtual Columns and Effective Functional Indexes in InnoDB

The virtual segments are never again appeared in the table. They are really “virtual”, which implies they are NOT put away in InnoDB lines (InnoDB stores the table information in its essential key records—a bunched list—so it implies that virtual segments won’t be available in InnoDB essential key records), consequently diminishing the general size of the table. This at that point takes into account speedier table sweeps and other substantial operations.

Since they are genuinely “virtual”, including and dropping virtual segments does not require a table revamp. Or maybe, enroll for oracle dba it just requires a brisk framework table refresh that registers the new metadata. This rolls out the diagram improvements straightforward and quick.

Making a file on a virtual section (just optional lists are permitted) will basically “appear” the virtual segment in the list records as the figured esteems are then put away in the auxiliary list, yet the qualities are not put away in the essential key (bunched list). So the table itself is still little, and you can rapidly gaze upward the figured (and put away) virtual segment esteems in the auxiliary record.

Once a record is made on a virtual segment, the incentive for such a virtual segment is MVCC logged in order to maintain a strategic distance from pointless re-calculation of the produced section esteem later when we need to play out a rollback or cleanse operation. Be that as it may, since its motivation is in keeping up the auxiliary list just, we will just log just up to a specific restricted length of the information so as to spare space, since our file has a key length impediment of 767 bytes for COMPACT and REDUNDANT for groups, and 3072 bytes for DYNAMIC and COMPRESSED column designs.
