Google Pub/Sub support on IBMi OS

We have tried to develop a solution to interact with Google Pub/Sub directly on the IBMi and have been unable to due to restrictions related to the processor on the IBMi. This has included attempts to run a Python coded solution on the IBMi directly. As a result, we are having to run several Windows servers operating as a middleware platform, running python code and ODBC in order to accommodate integration with a the Google Pub/Sub integration platform. There is obvious overhead to this and some concern about the long term viability of this solution. Given the excellent record the IBMi has with integrating to other platforms and technologies, I would like to propose the Google Pub/Sub be added to the list of messaging services made available to IBMi users.

    From what I read, you have tried installing a Python module for Google Pub/Sub, but it did not work on IBM i due to the module containing C code, correct? Python modules are often written in C (for performance reasons) and this can make it impossible to run the module on i because of compiler differences.

    Have you tried a nodejs solution? There is a npm module, which I just installed on an IBM i 7.5 without any problems:

    npm install @google-cloud/pubsub

    I did not test the package was working, so there could still be problems with this.

    If the nodejs module does not work, you should probably look at a Java solution - Manzan was mentioned below, but this seems to only have Google Pub/Sub as destination and not as a source.

    HTH.

    Seems like the format of my previous post was wrong and I do not seem to be able to change them, even if there is a edit button.

    I do a third try whith an other link.


    Have you checked out the open source project Manzan that is initiated by IBM?

    Manzan is still in technology preview, but according to the documentation it should have support for Google Pub/Sub.
