EF Core Extension Methods: Caching Options

NCache EF Core Extension Methods provide advanced caching capabilities through the CachingOptions class, enabling granular control over distributed data storage. These options allow developers to enrich cache items before insertion by configuring a QueryIdentifier for result set tracking, establishing Database Dependencies for automatic synchronization, and setting Cache Item Priority. Utilizing these API options ensures high performance and data integrity for Entity Framework Core applications in a clustered environment.

Prerequisites

• .NET

• Install the following NuGet packages in your client application:
  • Enterprise: EntityFrameworkCore.NCache
  • OpenSource: EntityFrameworkCore.NCache.OpenSource
• Include the following namespaces in your application:
  • Alachisoft.NCache.EntityFrameworkCore
  • Alachisoft.NCache.Runtime.Caching
• The cache must be running.
• Make sure that the data being added is serializable.
• For API details, refer to: CachingOptions, QueryIdentifier, Priority, CacheItemPriority, CreateDbDependency, StoreAs.

Configure EF Core Query Identifier and DB Dependency

The following sample configures the cache with the EF Core QueryIdentifier CustomerEntity and creates a DB dependency on the cache items with Absolute Expiration.

• .NET

var options = new CachingOptions
{
    QueryIdentifier = "CustomerEntity",
    CreateDbDependency = true,
    StoreAs = StoreAs.SeperateEntities,
    Priority = Runtime.CacheItemPriority.High
};

options.SetAbsoluteExpiration(DateTime.Now.AddSeconds(20));

Note

To ensure the operation is fail-safe, it is recommended to handle any potential exceptions within your application, as explained in Handling Failures.
