partition selection with message key

[Victor L]

I am looking for best method to keep consumption of messages in the same
order as client produced them, one thing i am looking at is using of
message key to select partition:
If a valid partition number is specified that partition will be used when
sending the record. If no partition is specified but a key is present a
partition will be chosen using a hash of the key.
Does that mean the same key for messages to be placed into the same
partition in order produced?
Thank you,
