I am glad to present the design for IO_CACHE's SEQ_READ_APPEND mode concurrency improvements. Jira task is MDEV-24676.

So, this is targeting only the scenario with multiple producers and one consumer? I see SEQ_READ_APPEND is only used for Relay Log on the slave. Afaiu, the relay log has only only one producer, the network io thread. Do I miss something here? Please clarify.
