Question about ‘SLAVE’ node’s process mothod

In MASTER-SLAVE mode, when a table is altered to be a s3 table. What will it do when it received the binlog?

Answer Answered by Daniel Black in this comment.

It will get exactly the same alter table engine=s3 so both the master and replica are refering to the same data.

See s3_replicate_alter_as_create_select for the behaviour in moving away from a s3 table.
