I assume you already know what/why/how to use Redis but more of trying to recall what are the data types of Redis is, then you've come to the right post.
Data Type | Command Prefix | Sorting | Unique | O(1) Operations | Good for |
---|---|---|---|---|---|
String | N/A | N/A | No | - | key-value store, counters |
List | L | sorted by insertion order | No | add in head, remove in tail | - |
Set | S | unordered | yes | add, remove, and test for existence | - |
Hash | H | - | - | - | - |
Sorted Sets | Z | sorted by score | yes | - | - |
