> if there are enough files in huge_workspace. A SHOW FILES command can produce the same effect. This issue proposes a new BOOT option named drill.exec.storage.file.recursive_listing_max_size with a default value of, say 10 000. If a file listing task exceeds this limit then the initiating operation is terminated with a UserException preventing runaway resource usage.
