Unfortunately, there is no way to delete an element from a Redis list faster than O(n) time complexity. This is because Redis does not provide a built-in command for directly deleting an element from a list by value without knowing the index.


If you need to delete an element from a Redis list based on its value, you will need to first find the index of the element and then use the LREM command to delete it. The LREM command has a time complexity of O(n), as it needs to traverse the list to find and remove the element.


If you frequently need to delete elements from a Redis list based on their value and performance is critical for your application, you may need to reconsider your data structure and use a different database solution that supports faster deletions for this use case.
