1. mset -> set multiple values for keys
ex: mset lang Java tech Redis
2. mget -> get multiple values for keys
ex: mget lang tech
3. strlen -> get length of the key
4. incr -> increment count my 1
5. incrby -> increment count of n
ex: set count 1
incr count
incrby count 10
6. incrbyfloat -> for floating value
7. To expire an value after some seconds
ex: set a 1
expire a 10 // here 10 is in seconds
8. flushall command will delete all key, value pairs from redis
9. To push data in a list
ex: lpush country India
lpush country US
10. To get all data from ths list
ex: lrange country 0 -1 (startRange, -1)
11. rpush will push the value to the last index of the list
ex: rpush country Australia
13. lpop to remove from list
ex: lpop country
14. llen command to get length of the list
15. lset is to change the object at the index n
ex: lset country 1 USA
16. linsert is the command to store data at any index
ex: linsert country before USA "Russia"
17. lindex command get the value from any particular index from list
ex: lindex country 2
18. sort <list_name> ALPHA to sort list of characters, just sort <list_name> for numbers

Didn't found the tutorial useful. Was expecting redis architecture explanation and various configurations, rather than running commands from CLI.
As mostly it would be integrated with an application that would perform data insertion and retrieval.

This is helpful, Have completed till Transactions.
Feedback as follows (Will keep on adding as I progress)
1. The usage of watch is not adequately explained. I had to refer to the Redis documentation to clear my understanding.
2. Would help if some more negative test cases are demonstrated to cement our understanding.
3. For the Scripts section, a little more detail would help, for example how the country capital example works(word by word)

Heads up, the instructor might be an amateur. He said FLUSHALL "deletes" all keys and values. It does the opposite - it stores them permanently on disk. 12:10.

I'm making API service with redis, that should deal with huge amout of people speedily. So i'm doing some stress test. If i do 2000 times of cotinuous 'get' from redis, without any interver between the execution, it takes long time for the first 'get' (0.03 second), and the shorter time(0.001 second) for the following every 'get's. And when I do 2000 times of 'get' with 3 seconds of intervals, like all of the 'get' being the first attempt, it takes long time for every 'get's. what is the reason, and how to fix this? i checked the maxmemory policy and it was 'noeviction'. I'm using python 3.11

Redis is a good one if you are making peer to peer applications
