TsavoriteCache is an IDistributedCache implementation using Tsavorite, the storage and query engine behind Garnet (a RESP server in .NET), providing a file-based local cache that persists between application executions.

services.AddTsavoriteCache(options =>
{
    // optionally configure
    options.Settings = new(baseDir: "cache");
});

then just use IDistributedCache as normal.
