Abstract

Embodiments of the invention provide a data updating method, device and equipment, a storage medium and a program product. The method comprises the steps of determining a data ID corresponding to at least one piece of updated data, determining a hash value corresponding to each data ID according to a preset rule, and configuring a Bloom filter according to the hash value corresponding to each dataID, so that a second computing node in the distributed system determines data needing to be updated according to the Bloom filter. According to the data updating method and device, the equipment, thestorage medium and the program product provided by the embodiment of the invention, the Bloom filter can be constructed by utilizing the data ID to realize transmission of the updating information, the data does not need to be updated in a one-by-one comparison mode, the data updating efficiency is improved, and the communication cost is reduced.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a data update method, device, equipment, storage medium, and program product. Background technique [0002] In a distributed system, multiple computing nodes can jointly use external storage devices to store data. For frequently accessed hotspot data, each computing node can cache a copy of the data in the local memory to avoid repeatedly reading data from the external storage device during calculation, which will consume a large amount of network resources and cause increased latency. When a computing node updates the original data in the external storage device, in order to ensure data consistency, the data copies of other computing nodes also need to be updated accordingly. [0003] At present, computing nodes in a distributed system need to compare data one by one when updating data, resulting in low update efficiency. Contents of the inventio...
