Hi! There is a sentence “All indexes are secondary indexes when using MyISAM as the database engine” in a place with discussion about non-clustered indexes, which makes it a bit hard to understand, what is meant my that “secondary index” exactly?
Do you mean that there is one clustered index which is in fact the table, and all other indexes are non-clustered = secondary?
