"I wonder how Uber adds an index to a table that already has 1B+ rows in it with mysql?"

"As long as you can shard "

Not sure how sharding helps with 1B+ tables when adding indices, care to share?

This is: "Split the index in your application code."

And then do your joins, in your application code.
