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. […]


Redis List Datatype are similar in C# world as LinkeList e.g LinkedList. Just like in LinkedList in C#, Redis can store items at Head or Tail of a List. The nice thing about them is that the insertion speed is just O(1), but do note that if you have a large list, the reading speed […]


I wanted to cover some security aspect of Redis, using Redis Password feature. Redis uses config file to provide a password for it. The config file is usually located at /etc/redis/redis.conf if you are using linux. Look for the SECURITY section.

If you are using docker you can set the option when you start […]


I wanted to go through the process of Redis running in AWS ElastiCache, since we have already covered Docker, Azure and plain vanilla Redis on Linux Server. Redis in AWS is under the umbrella of ElastiCache, where they offer Redis and Memcached. There are different type of nodes offered by AWS ElastiCache: Standard Memory Optimized […]


In this post I wanted to go through the process of Redis running in Azure. Redis in Azure is called Azure Redis Cache. Azure offers a secure access to a dedicated Redis cache, which allows you to connect from any Azure applications. There are certain tiers that are offered in Azure Redis: Basic Standard Premium […]


To get Redis running in Docker is quite easy. The windows installation follows but if you on the Linux platform, first you will need to install docker. Docker has very good documentation on how to get docker running on Linux. I personally use Ubuntu so would suggest you to give Ubuntu a try for Docker. […]
