@Mityuha Thanks for your report. I did some performance tests as you suggested on Py2.7, Py3.5, Py3.6, Py3.7, Py3.8. What I see is the performance improvement comes from [the usage...

@ericwoodall Is DBViz also using vertica-python? Have you toggled `connection_timeout` setting in dbt-vertica? Since there is no traceback message or log to look at, I think running the query on...

Please provide the version info for those packages you installed. Thanks.
