> Allow for FunctionAttributes to be updated
> -------------------------------------------
>
> Key: GEODE-10044
> URL: https://issues.apache.org/jira/browse/GEODE-10044
> Project: Geode
> Issue Type: Improvement
> Components: native client
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Minor
> Labels: pull-request-available
>
> *AS A* geode-native contributor
> *I WANT TO* to reset function attributes on-the-fly whenever a function
> attributes mismatch is detected on the client
> *SO THAT* FunctionAttributes can be changed during an upgrade scenario
> ----
> *Additional information.* Currently there is no exception being thrown from
> the server whenever a function attributes missmatch is detected. Instead, a
> function execution error is send to the client. So it remains to be tackled
> how the mismatch is going to be detected on the client side.
> *Also, for additional context,* this feature is designed in order to fulfill
> the following upgrade scenario:
> # A server function called ExampleFunction is deployed inside a cluster.
> This server function is defined with isHA=false
> # Function is executed several times from the client.
> # After some time, a new version of ExampleFunction jar is deployed. The new
> version of the server function is defined with isHA=true
> # After updating the server function, executions for this function inside
> the client should fail at most once, and after that, execute smoothly with
> the new function attributes.
