Interestingly even though MSSQL server uses an extremely different implementation of MVCC, it internally has a vacuum equivalent. (Which is required even when all MVCC support is disabled! It is used to enable efficient implementation of deletes, without having to use absurdly coarse locks). MSSQL just handles doing that cleanup silently in the background while exposing basically no no configuration except a trace flag that can turn it off. |
