Redis Series Part 4 thread is here!
Today, we're diving into Redis `Hashes`, simple explanations, and real-world example
#redis #series #thread 🧵
If you haven't read the previous thread about the list, check it out
Hash is essentially a collection of field-value pairs, where each field is a unique identifier and each value is the associated data. Just like JSON object or python dictionary. Everything inside the hash is a string.
In this example, we gonna store the user preferences when they want to receive threadletters in nooli.in
HSET: command adds one or more fields-values to key
HSET <KEY> field1 value1 field2 value2 Image

Redis Sets are a unique way to store your data! They allow for an unordered collection of strings with no duplicates. Perfect for managing sets of items without worrying about repetition
Let's dive in with an example, Say we want to give one lucky user a year of free membership to Nooli. With Redis Sets, users can enroll in the giveaway but only once, preventing duplicates. Easy and efficient!

Today, we will be learning about Redis' second data structure, which is the `list`. #thread 🧵
If you haven't read the first thread, check it out
Image
`List`: are like an array but we can use the list as a stack that follows Last-In-First-Out(LIFO) principle and a queue that follows First-In-First-Out (FIFO) principle
In this example, we gonna add users to our beta_list to send invitations in the near future

In the list, we use the push command, and to remove an item, we use the pop command. However, it's important to note that there are different types of push and pop commands available
