How to Treat a list like a stack?

To treat a list like a stack in Redis, you can use the following commands:

RPUSH to push items onto the stack.
LPOP to pop items off the stack.

For example, to create a stack for storing temporary data, you would use the following command:

RPUSH temp_data item1

This will push the item item1 onto the stack.
To get the item at the top of the stack, you would use the following command:

LPOP temp_data

This will return the item item1 and remove it from the stack.
You can also use the following commands to manage your stack:

LLEN to get the length of the stack.
LRANGE to get a range of items from the stack.
LREM to remove items from the stack.

For example, to get the length of the temp_data stack, you would use the following command:

LLEN temp_data

This will return the number of items on the stack.
To get the first two items on the stack, you would use the following command:

LRANGE temp_data 0 1

This will return a list containing the first two items on the stack.
To remove the item item1 from the stack, you would use the following command:

LREM temp_data 1 1

This will remove the first occurrence of the item item1 from the stack.
You can use these commands to implement a variety of stack-based applications in Redis, such as undo/redo functionality, function call stacks, and expression evaluation stacks.

Complete Guide to Redis Lists

When it comes to data structures, Redis offers a wide range of options to efficiently manage and manipulate your data and one of them is list. A list is an ordered collection of values associated with a unique index. Unlike arrays, Redis lists are not limited to a fixed size and can expand or shrink on per need basis. In real, it works like linked lists under the hood, which means adding or removing elements from the beginning or the end of the list is an efficient operation here having a time complexity of O(1) that is constant.
