[SOLVED] How we can use redis pipeline in django-redis?

How we can use redis pipeline in django-redis?

I want to use Redis pipeline (execute multiple commands) in django-redis.

We can use multi and exec command in Redis but how we can in django-redis ?

One solution is :

I have list of hash keys i want to get all hashes using of hash key.

On every iteration command send to redis server to fetch one by one hash.

for hashkey in feedlist:
    result = con.execute_command('hgetall',hashkey)
    print(result)

This is not a good idea instead of this we can use redis pipeline. But how i can achieve Redis pipeline in django-redis ?

Solution

Using Redis pipeline in django-redis.

 #first create pipline object using con object 
 pipeline = con.pipeline()

Inserting all commands into pipeline. Fetching all hash keys one by one and inserting them into pipeline.

 if feedlist:
     for post in feedlist:
         pipeline.execute_command('hgetall',post)
         #hgetall redis command to get all items of given hash key

Then call the execute() method on pipeline. It will return result back to result variable.

     result = pipeline.execute()

Redis transactions

MULTI, EXEC, DISCARD and WATCH are the foundation of transactions in Redis. They allow the execution of a group of commands in a single step.

Advantages

In one call we can fetch all the records.
Reduced network calls.
