[llvm-dev] [cfe-dev] Status of Bugzilla Migration

[Jeff Miller via llvm-dev]

>- This has to be done via GitHub API and we're rate limited to ~5000
requests per hour, so this means that the labelling will take ~20
hours. I was told that there is no way for us to have the API rate
limit increased.

This 5000 request per hour limit, is that per repo or per access token? Could we potentially make a pool access token from multiple github accounts to sidestep the issue? Say 20 tokens to do the migration in 1 hour?
