Rolling function not working as described in the docs

[wesselhuising]

In the docs, there is the same explanation for using rolling windows as when using Pandas. Although, in the case of BigFrames only a int is accepted while the docs state different. In this way, I can't use something like a str (7d) or a timedelta. These options are pretty vital to the rolling method in Pandas. Is there something I am overlooking (I looked in the source code of BigFrames and it seems that only an int is accepted as its arguments).

Thanks for the report! Assigning to @chelsea-lin as this week's oncall to investigate.

Also, CC @sycai who I believe has been assigned a similar issue.

Thank you. I've reassigned this to @sycai, who are already assigned on a related internal issue, 388916840.

Any update on this?

Hello, @wesselhuising !

We are actively filling the gaps between BigQuery Dataframe and Pandas. So far, the closed parameter has been added to rolling() (#1539), and the change has been released in 1.42.0. The on parameter and time-based range rolling are our next goals.

You can get notification via our CHANGELOG https://cloud.google.com/python/docs/reference/bigframes/latest/changelog and GitHub repository (https://github.com/googleapis/python-bigquery-dataframes).

Thank you very much!

Hey @wesselhuising !

Just want you to know that I have merged the PR: #1605 that enables time range rolling on dataframes and series.

The change is expected to be shipped in our next release.

Thank you very much!

Thank you very much, that is some great news! Looking forward to the next release.
