sijie commented on issue #1284: Improve FileInfoBackingCache URL: https://github.com/apache/bookkeeper/pull/1284#issuecomment-375420639 > Could you give a sequence of events for how the other race occurs? I am using your diagram and using the existing logic ``` | Read Fi CacheLoader | Write Fi CacheLoader | | ====================================== | ====================================== | | calls loadFileInfo | | | - checks fileInfos under read lock | | | | | | | calls loadFileInfo | | | - checks fileInfos under read lock | | | - create a file info and put into fileInfos under write lock | | - create another file | | | info and put it into | | | fileInfos under write lock | | ``` > Has the locking shown to be a problem in benching? it is a giant write lock. so every thread is blocking waiting for file lookup (which is done by the file loader).
