Abstract
A streaming data reading method based on an embedded file system, including: receiving a request for reading streaming data, when the requested streaming data exists in a disk, creating a new reading task for the request, allocating a storage space to the newly created reading task, and initializing relevant parameters; decomposing the reading task into a plurality of sub-tasks, each sub-task being responsible for reading a piece of physically continuous data, and caching same; extracting the data from the sub-task cache, packaging same according to a streaming data format, submitting the data to a caller of this reading task once one block of data is packaged, and releasing this sub-task and triggering the next sub-task after submission; and when all sub-tasks are successfully completed, reporting the normal completion of the task to the task caller, and waiting for the task caller to end the current reading task.
