Links

Links are created for transaction and function point needs:

Link type	Source and destination of link	Methods supported
belongsTo	From DotNet Redis Collection object to DotNet Redis Connection object	-
useInsertLink	Between the caller .NET Class / Method objects and Dotnet Redis Collection objects	StringSet StringSetAsync Add GeoAdd HashSet SetCombineAndStore AddItemToList AddItemToSet AddRangeToList AddRangeToSet CreateHashSet PushItemToList GetSetCount SetAsync
useDeleteLink	Between the caller .NET Class / Method objects and Dotnet Redis Collection objects	KeyDelete Remove RemoveAll KeyDump RemoveItemFromSet RemoveItemFromList PopItemFromList RemoveAsync
useSelectLink	Between the caller .NET Class / Method objects and Dotnet Redis Collection objects	StringGet StringGetAsync GeoRadius GeoRadiusAsync HashGetAllAsync HashGetAll Sort HashScan SetScan Get GetHashCount GetHashKeys GetListCount GetAsync GetAndRefresh GetAndRefreshAsync
useUpdateLink	Between the caller .NET Class / Method objects and Dotnet Redis Collection objects	StringIncrement StringIncrementAsync IncrementValueInHash

What results can you expect?

Some example scenarios are shown below:

Redis Connections and Collections

public class TestRedis 
    {

        // Configure Redis cache options
        RedisCacheOptions cacheOptions = new RedisCacheOptions("localhost");

        // Create a Redis cache instance
        public RedisCache cache = new RedisCache(cacheOptions);

        // Generate a cache key
        var cacheKey = "Company";

        public void deleteCompany()
        {   
            // Remove the cached item
            cache.Remove(cacheKey);
        }
    }

Insert Operation

public void insertCompany()
        {   
            // Store a value in the cache
            DistributedCacheEntryOptions options = new DistributedCacheEntryOptions();
            byte byteArray = Encoding.UTF8.GetBytes("1, TATA, IND");
            cache.Set(cacheKey, byteArray, options);
        }

Select Operation

public void selectCompany()
        {   
            // Retrieve the value from the cache
            var cachedValue = cache.Get(cacheKey);
        }

Update Operation

// Generate a cache key
var cacheKey = "myCounter";
public void update_()
        {   
            // Retrieve the value from the cache
            newValue = redisDb.StringIncrement(cacheKey);
        }

Delete Operation

public void deleteCompany()
        {   
            // Remove the cached item
            cache.Remove(cacheKey);
        }

Known Limitations

Cases in which the name is not resolved, Unknown connection/collection object will get created
