Abstract: A query optimization method performed by a data access node includes: receiving a query request that is used to query tenant data; searching for a cached optimal query plan for the query request; if the optimal query plan is found, using the optimal query plan as a target query plan; or if no optimal query plan is found, generating a target query plan corresponding to the query request; and submitting the target query plan to a database, where the target query plan is used by the database to query the tenant data. Logical access (query request) is converted into a query plan (physical data access) by the data access node rather than a database node. In addition, the optimal query plan is used for query, so as to reduce a query cost as much as possible, and improve query performance.
