Hello!

I suggest filing a feature request ticket against Apache Ignite JIRA. Best if you provide some reproducer project.

https://issues.apache.org/jira/browse/IGNITE <https://issues.apache.org/jira/browse/IGNITE>

You can also try some hybrid approach, such as firing a compute task from the entry processor, that would be hot redeployed properly.

    Hi Ilya,

    Updating the user version does not affect this issue.

    Adjusting the deploymentMode parameter also has no effect on this
    issue.

    Hello!

    Did you try changing user version between deployments?

        Hi Ilya,

        This issue exists in both versions 2.8 and 2.8.1.

        Hello!

        Did that work under 2.8? Can you check

        If it wasn't, then maybe it is not implemented in the first
        place. If it is a regression, we could try to address that.

        Regards.
