            Redis Pipeline have different implement for Jedis and Lettuce.

            In Jedis, pipeline will block 1 connection and send all pipeline commands together with same connection(bio)

            In Lettuce, pipeline use Netty nio as network connection tool. So during the pipeline execute in client side, it will not block the connection(generally lettuce will use single connection). And when pipeline execute(send to Redis), it will select 1 connection from Netty.

            And both libraries are using same connection for pipeline commands as they will send all commands together in a single network request.

            Find your pod name using

            kubectl get pods

            Log into the running pod and execute bash:

            kubectl exec -it yourpodname bash

            Execute ps command with -aux to see more details on running processes and filter for java

            ps -aux | grep java

            Example output:
