Abstract: This disclosure provides a query task execution method, apparatus, computer device, storage medium. The method includes: receiving a query task for a target data table; determining at least one candidate degree of parallelism for executing the query task based on a first number of child tables obtained by pre-partitioning the target data table; selecting a target degree of parallelism within a preset range of degrees of parallelism from the at least one candidate degree of parallelism; and determining required computing units according to the target degree of parallelism, and evenly allocating the child tables to the computing units which concurrently execute the query task based on the allocated child tables.

Abstract: The present disclosure relates to a method for managing cache data, an apparatus, a storage medium and an electronic device, the method includes: acquiring a remaining available space of a solid-state disk for storing cache data; upon the remaining available space being less than a first space threshold, determining a first target fragment group in the solid-state disk that has the greatest garbage proportion, each fragment group including a first number of fragments, and each fragment corresponding to a second number of contiguous logical address spaces in the solid-state disk; and purging the cache data in the first target fragment of the first target fragment group that has the greatest garbage proportion, with this method, the space utilization rate of the solid-state disk can be improved.
