For large repositories, buckets can be slow to iterate over. Use memory backed buckets to reduce file access for both doc and license files. This can speed up builds by up to 2/3 on large repositories by avoiding iterating over os storage buckets. As an example running build of a single proto file in a large workspace of 96k files takes 1.60s with
v1.36.0
, 1.06s withv1.31.0
and 0.56s with this change.This is a simpler approach to #3230 but can be used in conjunction with it.
