Hi!
I’ve long waited for mongo 6.0 release to start using the pre-image feature in change streams.
I upgraded my mongo version but I noticed that the mongocxx does not support this new feature yet.
Is there a workaround to still read the pre-image data using mongocxx 3.6.6 version?
Also, I tried doing a POC with pymongo and got into the same issue - 4.2.0 should support it but I can’t seem to be able to upgrade to it (currently latest I can install is pymongo 4.1.1)
What is stopping you from upgrading PyMongo to 4.2?
Hi @Bernie_Hackett, thanks for the reply!
when running:
python3 -m pip install --upgrade pymongo==4.2.0
I get:
ERROR: Could not find a version that satisfies the requirement pymongo==4.2.0 (from versions: 0.1rc0, 0.1.1rc0, 0.1.2rc0, 0.2rc0, 0.3rc0, 0.3.1rc0, 0.4rc0, 0.5rc0, 0.5.1rc0, 0.5.2rc0, 0.5.3rc0, 0.6, 0.7, 0.7.1, 0.7.2, 0.8, 0.8.1, 0.9, 0.9.1, 0.9.2, 0.9.3, 0.9.4, 0.9.5, 0.9.6, 0.9.7, 0.10, 0.10.1, 0.10.2, 0.10.3, 0.11, 0.11.1, 0.11.2, 0.11.3, 0.12, 0.13, 0.14, 0.14.1, 0.14.2, 0.15, 0.15.1, 0.15.2, 0.16, 1.0, 1.1, 1.1.1, 1.1.2, 1.2, 1.2.1, 1.3, 1.4, 1.5, 1.5.1, 1.5.2, 1.6, 1.7, 1.8, 1.8.1, 1.9, 1.10, 1.10.1, 1.11, 2.0, 2.0.1, 2.1, 2.1.1, 2.2, 2.2.1, 2.3, 2.4, 2.4.1, 2.4.2, 2.5, 2.5.1, 2.5.2, 2.6, 2.6.1, 2.6.2, 2.6.3, 2.7, 2.7.1, 2.7.2, 2.8, 2.8.1, 2.9, 2.9.1, 2.9.2, 2.9.3, 2.9.4, 2.9.5, 3.0, 3.0.1, 3.0.2, 3.0.3, 3.1, 3.1.1, 3.2, 3.2.1, 3.2.2, 3.3.0, 3.3.1, 3.4.0, 3.5.0, 3.5.1, 3.6.0, 3.6.1, 3.7.0, 3.7.1, 3.7.2, 3.8.0, 3.9.0, 3.10.0, 3.10.1, 3.11.0, 3.11.1, 3.11.2, 3.11.3, 3.11.4, 3.12.0, 3.12.1, 3.12.2, 3.12.3, 4.0, 4.0.1, 4.0.2, 4.1.0, 4.1.1)

Anyway, I was able to do a POC with mongosh, but I still want to have this working with mongocxx - any idea would be appreciated.
That’s odd. Installation works fine for me locally:
sigstop@devbox ~ $ python -m venv installtest
sigstop@devbox ~ $ source installtest/bin/activate
(installtest) sigstop@devbox ~ $ which python3
/home/sigstop/installtest/bin/python3
(installtest) sigstop@devbox ~ $ python3 -m pip install --upgrade --no-cache-dir pymongo==4.2.0

What version of Python are you using on which operating system?
For the C++ driver, this feature has been implemented and committed to the master branch of the driver. It will be released in version 3.7.0, which will be out soon.
You may be running into a bug in pip. It would be helpful to post your pip version: python3 -m pip --version
Please upgrade to the latest pip and then try to install pymongo 4.2 again: python3 -m pip install --upgrade pip
Thanks for the replies!
@Bernie_Hackett
do you have a time estimation for 3.7.0 release?
@Shane this is the output:
python3 -m pip --version
pip 21.3.1 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)
Aha. PyMongo 4.2.0 only supports Python 3.7+. We hope ro release C++ driver 3.7.0 in the next week or so.
thanks for the reply!
looking forward to using the new 3.7.0 C++ driver
