Entity Framework Core Distributed Cache with Redis with fully support for asynchronous environments. That increase performance drastically.
public void ConfigureServices(IServiceCollection services) {
//Create instance of RedisCache
ICacheProvider cacheProvider = new RedisCacheProvider(Configuration.GetConnectionString("Redis"));
services.AddDbContext < AppDbContext > ((serviceProvider, options) => {
options.UseSqlServer(Configuration.GetConnectionString("Default"));
//Do not use like that
//options.UseDistributedSecondLevelCache(new RedisCacheProvider);
//This method called with every request, and it will spawn many redis cache instances
options.UseDistributedCache(cacheProvider);
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2).AddControllersAsServices();
}By default all caching queries are use distributed lock between each nodes, to order only those instance(node,server) and thread who first acquire lock, will setup cache for this request.
return await _appDbContext.Products.AsCaching(TimeSpan.FromSeconds(30)).Where(x => x.Id != Guid.Empty).ToListAsync();if you want to use it only on one server, it makes no sense to use distributed lock. You can disable it like:
var cacheOptions = new CachingOptions() {
Expiry = TimeSpan.FromSeconds(30),
DistributedLock = false
};
return await _appDbContext.Products.AsCaching(cacheOptions).Where(x => x.Id != Guid.Empty).ToListAsync();
