The invention aims to provide a database data recovery method and a database firewall. The SQL operation of the user is detected, when deletion of the data table is involved, the SQL content is replaced, data backup is conducted on the corresponding data table, meanwhile, a response of successful execution is still made to the user, and user operation is not affected; meanwhile, when the protector needs to be recovered, the reverse operation can be executed through the SQL command, and the data can be rapidly recovered; meanwhile, different backup modes are executed according to different database protocols and different types of deletion operations, the advantages of the database can be fully utilized, backup and recovery processing can be accelerated, and the protection efficiency of a database firewall is improved.

The invention provides a request scheduling method for a multi-tenant system and related equipment. The multi-tenant system comprises a plurality of tenants, and the plurality of tenants share one storage system. The method comprises the following steps: acquiring a target operation request which is initiated by a target tenant in the plurality of tenants and aims at the storage system; obtaining an I / O resource allocation amount pre-allocated for the target tenant from the total I / O resource amount pre-configured for the multi-tenant system; calculating a scheduling moment corresponding to the target operation request according to the I / O resource allocation quantity of the target tenant and a scheduling moment corresponding to a historical operation request initiated by the target tenant last time; and determining whether the scheduling moment of the target operation request meets a scheduling condition, and if yes, scheduling the target operation request to execute a plurality of operations contained in the target operation request.

This application discloses a data loading method for a RISC-V vector processor, comprising: executing a data preloading instruction to load target data from a first memory to a second memory; wherein the data preloading instruction runs in parallel with ordinary instructions running before the data loading instruction; and executing the data loading instruction to load the target data from the second memory into the RISC-V vector processor. This method can improve the data processing speed and performance of the RISC-V vector processor. This application also discloses a data loading device, apparatus, and computer-readable storage medium for a RISC-V vector processor, all of which have the above-mentioned technical effects.
