EFFICIENT BUFFER POOL PAGE PRE-FETCHING FOR DATABASE CLUSTERS |
| 摘要 |
A method for use in a database cluster is provided. A first transaction is received at a first node of the database cluster. A page pre-fetch request corresponding to the first transaction is generated whilst executing the first transaction at the first node. The page pre-fetch request is indicative of at least one database page that is referenced by the first transaction. Moreover, the page pre-fetch request is added to a replication write-set of a second transaction at the first node. Subsequently, the replication write-set of the second transaction, along with the page pre-fetch request, is communicated to a second node of the database cluster. |
