Does joins in Tableau effect performance

0 votes
I have tables A, B, C, and D in a MySQL database. B, C, and D have a relationship with A, but B, C, and D do not have a relationship with each other. Because data must exist in the form of a table in order to make graphs in Tableau, I constructed a linked relationship between them as follows: A-(right join B), A-(right join C), A-(right join D) will result in the presence of all rows in B, C, and D. I'm curious if this type of join has an impact on data base performance when a single table is built in Tableau with all of the fields from A, B, C, and D? Also, am I using the proper procedure?
