--------------------------------------
Summary: Add ability to configure empty file behavior in IOs
Key: BEAM-12211
URL: https://issues.apache.org/jira/browse/BEAM-12211
Project: Beam
Issue Type: New Feature
Components: io-java-files, io-py-common
Reporter: Daniel Oliveira
This is a general feature request based on frequent questions I see on Stack
Overflow. I often see questions about how to get an empty file instead of no
file when a PCollection is empty, or vice versa for IOs that create empty
files. In other words, whichever approach is taken, there's users that will
want the opposite approach.
It seems the best approach here would be to add some kind of common code
(FileIO maybe?) that could either open files for writing in Setup or lazily in
ProcessElements.
Regardless of the approach taken, this bug is basically for investigating this
feature for feasibility and maybe holding sub-tasks/blocking bugs for tracking
implementation.
