Key-value stores are a subset of non-SQLdatabases. They provide limited functionality but high performance. In this video, learn more about key-value stores.
- [Narrator] An important subset of databases are…key-value stores.…In our example in this chapter, we will use Redis for that.…While key-value stores are very limited, they are also…very powerful and fast.…Let's look at the basic principles of them.…So if you ever worked with some associative array with…some programming language this is what it's actually about.…So you have a huge table where you store all the data and…every piece of data is associated with a key.…
Let's look at the example here.…We have maybe some key A and data stored here and we have…some key B and some data stored there, and we have some…key C and we store binary data there.…So that's the very basic principle of key-value stores.…The interesting part is that key-value stores support…different kinds of data types for key and as well for value.…Our key that is now here C could as well be some binary.…
Redis comes with some basic data types as well and we will…now look at the hash map data type because we will use…it in this chapter.…In this case, you have some key and then you have some hash…
