What are the large file caching mechanisms?

Large file caching mechanisms include file cache, memory cache, distributed cache, object storage, etc. Detailed introduction: 1. File cache: Save frequently accessed files or data in the cache to reduce the number of accesses to the original file or data source, thereby reducing network transmission and disk I/O operations and improving performance; 2. Memory cache : Use memory as a cache storage medium to store frequently accessed large file data in memory for quick access; 3. Distributed cache: Distribute large file data to multiple cache servers to improve cache availability and scalability Sex and so on.

Operating system for this tutorial: Windows 10 system, Dell G3 computer.

Large file caching mechanisms mainly include the following:

1. File caching: Save frequently accessed files or data in the cache to reduce access to original files or data sources times, thereby reducing network transmission and disk I/O operations and improving performance.
2. Memory cache: Use memory as a cache storage medium to store frequently accessed large file data in memory for quick access.
3. Distributed cache: Spread large file data across multiple cache servers to improve cache availability and scalability.
4. Object storage: Use object storage systems (such as Amazon S3, Google Cloud Storage, etc.) as the storage medium for large file cache, store large files in the form of objects in the cloud, and access them through high-speed networks.

When implementing a large file caching mechanism, the issue of cache invalidation needs to be considered. In order to ensure that the large file read from the cache is consistent with the data in the original file or data source, it is necessary to clear the corresponding data in the cache when the data in the original file or data source changes. In addition, cache capacity and performance issues also need to be considered to ensure that the cache can effectively improve system performance. At the same time, attention needs to be paid to the proper management and storage of metadata of large files to ensure the correctness and integrity of the metadata.
