In this blog post I wanted to cover how to use Redis with AspNetCore WebAPI. Most of my examples have been covering using console application since I wanted to explain the core concepts of Redis and the functionality. Now lets see how you can use it in a Web Application. Create the webapi To start […]

If you are serious in running Redis, you will want to run it under HA mode (High Availability). So far for learning purpose you can run a single instance of redis under your docker environment quite easily, but what if you need to run it in production? This is where Redis Sentinel comes in to […]
Redis GeoSpatial data sets are actually just SortedSets in Redis, there is no secret about it. Basically it provides an easy way to store geo spatial data like longitude/latitude coordinates into Redis.Lets look at some of the commands that Redis provides for Geo Spatial data. Redis Geo Datatype – Operations GEOADD: Adds or updates one […]
Redis Lua Scripting Redis provides a way to extend its functionality on the server side by providing support for Lua Scripting. If you are coming from a relational database world, you already know that you can use Stored Procedures to extend functionality of your relational database. Now, you may also know that some people do […]
Redis Transactions Redis provides a way to do Transactions, but the transactions are somewhat different than what you know from a SQL Relational Database perspective. In SQL Relation Database world you can executed partially and then rolled back the entire transaction. While Redis uses the MULTI and EXEC commands where every command passed as part […]
Redis provides a way to use Pipeline Batching to send messages to Redis but first we must understand that Redis uses tcp request response protocol, some may know it as client server model. If you are coming from a web http world, you will have no issue understanding client server, where the browser acts like […]
Redis Pub Sub, somehow may sound weird that it provides such a functionality since when you think of Redis the first thing that comes to mind is of a cache key value store. But indeed Redis does allow us to use the messaging paradigm by using channels to publish messages and for subscribers to listen […]
Redis HyperLogLog is used for calculating the cardinality of a set or non mathematically speaking it is a probabilistic data structure used to count unique values. Basically it is an algorithm that use randomization such that it can provide an approximation of the number of unique elements in a set by just using a constant […]
Redis Sorted Sets are similar to Sets, with unique feature of values stored in Set called scores. The score is used in order to take the sorted set ordered, from the smallest to the greatest score. Just like in Sets, members are unique but scores can be repeated. Sorted Sets are ideal for storing index […]
Redis Sets Datatype are similar in C# world as HashSet, they are an unordered collection used for storing strings. One of the great benefit of Redis Sets is that the operation of add, remove, and testing for existence of items is of constant time of O(1) regardless of the number of items in the Set. […]
