Since you seem to be working with a fixed and finite number of ids, it would be easier to shuffle them once and write them to a file. Then each time you need one, take the last one in the file and truncate it so it cannot be used again. Once you get to an empty file, shuffle them again and re-write the file.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
