-------------------------------
Summary: Move isHA, isHA, hasResult, optimizeForWrite from the
Function interface to the Execution interface
Key: GEODE-727
URL: https://issues.apache.org/jira/browse/GEODE-727
Project: Geode
Issue Type: Bug
Reporter: Dan Smith
sHA, hasResult, and optimizeForWrite are methods on Function that the user can
override. However, that makes it harder to write lambda expressions for
functions, because if you want to set one of these parameters you can now
longer use a lambda.
Also the function service API provides a way to invoke functions using a string
id. For example FunctionService.onServer().execute("MY_FUNCTION_ID"). If we
remove these extra methods from the Function interface, this code will no
longer need to look up the Function on the client and the Function class will
not have to exist on the client any more.
We will add isHA(boolean), hasResult(Boolean) and optimizeForWrite(boolean) to
the Execution interface. These methods will be deprecated on the function
interface and be given default values. Unfortunately, if someone invokes a
function on a client given the string id, we will still need to look up the
function class for now in case they have specified these parameters on their
function. But in another release we can remove the deprecated parameters and
stop using them.
