Embodiment Construction

[0028] The present invention is described in detail below in conjunction with accompanying drawing and example, makes above-mentioned advantage of the present invention more clear:

[0029] The embodiment of the present invention aims at the problem of insufficient data reading efficiency and concurrency in existing embedded streaming services, and proposes a streaming data reading method based on an embedded file system. The method decomposes tasks , which improves the efficiency of reading data, adopts the asynchronous reading mechanism to ensure high concurrent reading of streaming data, and also allows users to change the end offset in the process of reading data, which enriches the user's operation mode and is used in streaming service applications. There are great advantages in the scene.

Abstract

The invention provides an embedded file system-based reading method for streaming data. The method comprises the following steps: receiving a request for reading the streaming data, creating a reading task for the request when the requested streaming data exist in a disk, distributing storage space for the new reading task and initializing relevant parameters; decomposing the reading task into a plurality of subtasks, wherein each subtask is responsible for reading a piece of physically continuous data, and caching the data; fetching the data from subtask cache, performing encapsulation according to the format of the streaming data, submitting to a calling party of the reading task after a piece of data is encapsulated each time, and releasing the subtask after data submission is competed and triggering the next subtask; when all the subtasks are successfully finished, reporting that the tasks are normally finished to the task calling party, and waiting the task calling party to end the current reading task. According to the embedded file system-based reading method provided by the invention, high-throughput and high-concurrence reading of the streaming data is facilitated, and the problem that the concurrence performance of a server is low when a large number of users visit hot data is effectively solved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a streaming data reading method based on an embedded file system. Background technique [0002] With the rapid development of the Internet and multimedia industry, various storage technologies and storage systems have also been developed rapidly. These storage systems provide convenient, fast and efficient storage and access services for massive Internet information and multimedia data information. [0003] Embedded system resources are limited and the structure is simple. Due to its particularity and specialization, general-purpose operating systems and file systems are rarely used in embedded systems, but file systems are customized for embedded systems for specific application scenarios; it can be embedded The application range of embedded systems is very wide. It is impossible to have a file system that dominates all embedded systems. It is suitable for all situations r...
