Addcolumns with text

What do we think is the best way with extremely large tables to append one column to another with dax assuming both  are values?   I am using crossjoin and it's killing me with processing load.   S...

    charleshale here how dax will change:

     

    Filter Intersect = 
VAR __countEmails = 
CALCULATE ( 
    COUNTROWS ( EmailSubs ), 
    USERELATIONSHIP ( EmailSubs[Email], Lookup[Email] )   //in case this EmailSubs table has inactive relatiobship
)  
VAR __countUsers = 
    CALCULATE ( 
        COUNTROWS ( 'Registered USers' ), 
        USERELATIONSHIP ( 'Registered USers'[Registered User], Lookup[RegsteredUser#] )    //in case Registered USers table has inactive relatiobship
    )
RETURN
IF ( __countEmails  == BLANK() ||  __countUsers == BLANK() || MAX ( Lookup[Email] ) == BLANK(), BLANK() , 1 )

charleshale looking at your pbix file, what is your goal? What you want the expected result? For a second forget about the solution to how to get there.

On the PBIX file the only intersect between email and registered user IDs would be the first row if these were the 3 tables ([email protected]).   Basically, another way to ask the question is "what's the best way to do a 3 way intersect!"?    (PS assuming there are inactive relationships involved)
