@TomAugspurger Request for review. Do we need to set the min version as mention in https://github.com/pandas-dev/pandas/issues/33360#issuecomment-610412310 @alimcmaster1 need help in understanding the reason for build failures, should we just re-run it ? > @alimcmaster1 need help in understanding the reason for build failures, should we just re-run it ?

Sure - if you merge master this should now be fixed.  @jreback Green @sumanau7 please see my comments above. We need to change the min supported before doing this https://pandas.pydata.org/pandas-docs/stable/getting_started/install.html#optional-dependencies it’s currently 0.8.0 you are proposing 0.12.0 right?  > @sumanau7 please see my comments above.

@alimcmaster1 Have done that change, can you please verify if these are the only places where this change is required > @alimcmaster1 Have done that change, can you please verify if these are the only places where this change is required

You will also need to update `_optional.py` Note current default behaviour of pandas `read_gbq` is tdqm progress bar. This change makes the default no progress bar right?. Do we want to be consistent with pandas_gbq and use tdqm by default? 

(From @TomAugspurger comment here https://github.com/pandas-dev/pandas/issues/33360#issuecomment-610401113 sounds like we should have same default :) ) This looks pretty much there to me. (Just need to decide on this [point](https://github.com/pandas-dev/pandas/pull/33477#issuecomment-613743313))

@sumanau7 looks like some of the tests are failing (logs on longer available) mind taking a look? - https://github.com/pandas-dev/pandas/pull/33477/checks?check_run_id=588645024 Looks like this build job it failing - (not publishing back to PR) https://github.com/pandas-dev/pandas/pull/33477/checks?check_run_id=588645024

 @sumanau7 could you update as per Jeff’s comments? Thanks! thanks @sumanau7
