Broken Pipe Error Redis
Redis' String data type can be at most 512MB.
We are trying to SET pickled object of size 2.3GB into redis through redis-py package. Encountered the following error.

BrokenPipeError: [Errno 32] Broken pipe
redis.exceptions.ConnectionError: Error 104 while writing to socket. Connection reset by peer.

I would like to understand the root cause. Is it due to input/output buffer limitation at server side or client side ? Is it due to any limitations on RESP protocol?  Is single value (bytes) of 2.3 Gb allowed to store into Redis ?

import redis
r = redis.StrictRedis(host='10.X.X.X', port=7000, db=0)
pickled_object = pickle.dumps(obj_to_be_pickled)
r.set('some_key', pickled_object)

Client Side Error

BrokenPipeError: [Errno 32] Broken pipe
