Messages written to the partition leader are not immediately readable by consumers regardless of the producer’s acknowledgement settings.

When all in-sync replicas have acknowledged the write, then the message is considered committed, which makes it available for reading. This ensures that messages cannot be lost by a broker failure after they have already been read.
