Can i use autopipeline feature with all keys and hashes ?

[taltal78]

Hi,
Reading autopipelining docu https://github.com/redis/ioredis#autopipelining it states:

When using Redis Cluster, one pipeline per node is created. Commands are assigned to pipelines according to which node serves the slot.
A pipeline will thus contain commands using different slots but that ultimately are assigned to the same node.
Note that the same slot limitation within a single command still holds, as it is a Redis limitation.

To make sure i understand, autopipieline is supported with any key that i use?
multiple keys (even in same node) are scattered among different hash slot (According to key) - so this sill works?
if some keys (in same node) are scattered in 3 hashslot, there wil be one pipeline with 3 commands?

what are the drawbacks or when not to use autopipelining ?

Will it be more beneficial to create pooling? (or in addition to autopipelining)

Thank you
