Implementing Distributed Locking with Redis and IDistributedLock Distributed locking is a critical feature for ensuring resource safety in distributed applications. Here’s how you can implement a distributed lock using the IDistributedLock interface and Redis as the backing store, leveraging the StackExchange.Redis library. Step 1: Implement the IDistributedLock Interface Let’s start by creating the RedisDistributedLock class to implement the IDistributedLock interface: using StackExchange.Redis; using System; using System.Threading.Tasks; public class RedisDistributedLock : IDistributedLock { private readonly IDatabase _database; private readonly string _lockKey; private string _lockToken; public RedisDistributedLock(IDatabase database, string lockKey) { _database = database; _lockKey = lockKey; _lockToken = Guid.NewGuid().ToString(); } public async Task<bool> AcquireLockAsync(string resource, TimeSpan leaseTime) { _lockToken = Guid.NewGuid().ToString(); return await _database.StringSetAsync(resource, _lockToken, leaseTime, When.NotExists); } public async Task RenewLockAsync(TimeSpan leaseTime) { if (!await _database.StringGetAsync(_lockKey).ConfigureAwait(false).Equals(_lockToken)) { throw new InvalidOperationException("Cannot renew a lock that is not held."); } await _database.KeyExpireAsync(_lockKey, leaseTime); } public async Task ReleaseLockAsync() { var token = await _database.StringGetAsync(_lockKey); if (token == _lockToken) { await _database.KeyDeleteAsync(_lockKey); } } public void Dispose() { ReleaseLockAsync().GetAwaiter().GetResult(); } } Step 2: Create a Sample Console Application Next, build a console application to demonstrate the functionality of the RedisDistributedLock: ...

Mastering Aspect-Oriented Programming (AOP): Concepts and Examples Aspect-Oriented Programming (AOP) is a programming paradigm that takes modularity to the next level. It allows you to neatly separate cross-cutting concerns like logging, security, or transaction management from your main business logic. Think of it as an enhancement to Object-Oriented Programming (OOP) that brings even more structure and reusability to your codebase. link to link to Key Concepts of AOP Here’s a quick dive into the foundational elements of AOP: ...

To create a code generator that automatically caches any function with a cache attribute that takes a duration, you can use a source generator in .NET. Source generators allow you to generate additional source code at compile time. Step 1: Define the Cache Attribute First, define the cache attribute that will be used to mark methods for caching: using System; [AttributeUsage(AttributeTargets.Method, Inherited = false, AllowMultiple = false)] public sealed class CacheAttribute : Attribute { public CacheAttribute(int durationInSeconds) { DurationInSeconds = durationInSeconds; } public int DurationInSeconds { get; } } Step 2: Create the Source Generator Next, create the source generator that will generate the caching logic for methods marked with the CacheAttribute. ...

RedisDistributedLock Implementation in Aspect-Oriented Programming (AOP) Aspect-Oriented Programming (AOP) lends itself well to distributed resource management tasks such as locking. Below is an implementation of a Redis-based distributed lock using the StackExchange.Redis library, focusing on resource isolation and concurrency control. RedisDistributedLock Class Here is the complete implementation: using StackExchange.Redis; using System; using System.Threading.Tasks; public class RedisDistributedLock : IDisposable { private readonly IDatabase _redisDb; private readonly string _lockKey; private readonly string _lockValue; private bool _acquired; public RedisDistributedLock(IDatabase redisDb, string resourceKey) { _redisDb = redisDb; _lockKey = $"lock:{resourceKey}"; _lockValue = Guid.NewGuid().ToString(); // random token } /// <summary> /// Attempts to acquire a lock for the specified lock key with a given expiry. /// </summary> /// <param name="expiry">Duration for lock expiry.</param> /// <returns>True if the lock was acquired; otherwise, false.</returns> public async Task<bool> AcquireAsync(TimeSpan expiry) { _acquired = await _redisDb.StringSetAsync( key: _lockKey, value: _lockValue, expiry: expiry, when: When.NotExists); return _acquired; } /// <summary> /// Releases the lock if it’s still held by this instance. /// </summary> public async Task ReleaseAsync() { if (_acquired) { // Verify token before deleting. var currentValue = await _redisDb.StringGetAsync(_lockKey); if (currentValue == _lockValue) { await _redisDb.KeyDeleteAsync(_lockKey); } _acquired = false; } } /// <summary> /// Cleanup method ensuring the lock is freed. /// </summary> public void Dispose() { ReleaseAsync().GetAwaiter().GetResult(); } } Acquiring and Releasing the Lock Using the RedisDistributedLock class to acquire and release locks ensures concurrency control in distributed systems. ...

Mastering the Retry Pattern: Enhancing Application Resiliency The retry pattern is a crucial design technique for improving the resiliency of applications, especially when dealing with transient faults in external systems. Let’s explore its purpose, implementation, and how it contributes to robust architecture. Purpose of the Retry Pattern Automatic Retries: Enables applications to automatically retry a failed operation due to transient faults. Graceful Error Handling: Improves user experience by addressing errors seamlessly. Increased Reliability: Allows applications to recover from temporary issues, ensuring dependable performance. Key Concepts of the Retry Pattern Transient Faults: Temporary issues like network glitches, timeouts, or service throttling that are likely to succeed upon retry. Retry Interval: The delay between attempts, which can follow a fixed interval, exponential backoff, or a custom logic. Max Retry Attempts: Specifies the maximum number of retries before declaring the operation as failed. Implementation Example in C# Here’s how to implement a retry pattern using C#: ...

Message Envelopes in Message-Based Software Development In message-based software development, message envelopes are a design pattern used to wrap the core message with additional metadata. This metadata helps the messaging system process, route, or interpret the message without needing to understand its actual content. Key Features of Message Envelopes Header and Body Separation: The header contains metadata like routing information, encryption details, or timestamps. The body holds the actual message payload. Flexibility: ...
