> Uber JIRA to track things needed for Azure Data Lake to be considered stable and adl://
ready for wide use.
> Based on the experience with other object stores, the things which usually surface once
a stabilizing FS is picked up and used are
> * handling of many GB files, up and down, be it: efficiency of read, when the writes
take place, file leakage, time for close() and filesystem shutdown
> * resilience to transient failures
> * reporting of problems/diagnostics
> * security option tuning
> * race conditions
> * differences between implementation and what actual applications expect
