[jira] [Updated] (BEAM-2264) Re-use credential instead of
generating a new one one each GCS call
[ https://issues.apache.org/jira/browse/BEAM-2264?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Luke Cwik updated BEAM-2264:
----------------------------
Description:
We should cache the credential used within a Pipeline and re-use it instead of generating a new one on each GCS call. When executing (against 2.0.0 RC2):
{code}
python -m apache_beam.examples.wordcount --input "gs://dataflow-samples/shakespeare/*" --output local_counts
{code}
Note that we seemingly generate a new access token each time instead of when a refresh is required.
