------------------------------------
Summary: Improve performance when staging files
Key: BEAM-814
URL: https://issues.apache.org/jira/browse/BEAM-814
Project: Beam
Issue Type: Improvement
Components: runner-dataflow
Reporter: Daniel Halperin
Assignee: Daniel Halperin
Priority: Minor
Right now, {{PackageUtil}} hashes/compresses/sizes files, checks if they have
already been staged, and uploads them if not, completely serially.
There is some low-hanging fruit to parallelize this.
