how can I remove index that not building yet( and may not online)?
why i want do it, because it takes long time (regarding resource issue) and I’d like remove.
it and use view directly

Looks like you’ve censored it (fair enough!) but have you specified a custom name for the Primary index? If so you would need to drop the index like any other (non-Primary) one, e.g.:
DROP INDEX `beer-sample`.`my_primary_index`

From the docs here:

Important: Named primary indexes that are created using CREATE PRIMARY INDEX, can only be dropped using the DROP INDEX command.

Oooooop!
I could not believe that I made this very awful wrong.
you are right and that worked.
Thanks.
