Abstract

The embodiment of the invention provides a data read-write method and system, electronic equipment and a storage medium, and the method comprises the steps: receiving request information transmitted by a control layer, transmitting to-be-read data to the control layer through a lockable data reading channel, receiving rewritten data sent by the control layer through a lockable data updating channel, and sending the rewritten data to the data layer through a lockable data exchange channel,, wherein at least one of the data reading channel and the data updating channel and the data updating channel and the data exchange channel is in a locking state. Visibly, the cache layer is inserted between the control layer and the data layer, so that the requirement that multiple threads read the samedata at the same time during IO high concurrency is met, and meanwhile, after the cache layer is inserted, orderly transmission of the data in the cache layer is effectively guaranteed through all lockable data channels.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a data reading and writing method, system, electronic equipment and storage medium. Background technique [0002] The normal operation of APP (Application, application program) is based on the data reading and writing system, and the data exchange in the data reading and writing system is based on the IO (Input / Output, input / output) operation between the control layer and the data layer Achieved. [0003] When one app is running or multiple apps are running at the same time, there will be high concurrency of IO operations of multiple threads, that is, the same data in the data layer is read or rewritten by multiple threads at the same time, causing each thread to run and wait. In order to solve the above problems, the usual method is to set up a cache layer between the data layer and the control layer, so that the data to be read and rewritten are stored in t...
