In my > case, that means traversing everything in my home directory, which is *a lot* > (and includes remotely mounted directories). > https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/util/FileIOChannelFactory.java#L109 > This is very wasteful and should be fixed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
