John Blum updated GEODE-28:
---------------------------
Description:
If developers want to "implement" _Apache Geode_ {{Functions}} using [_Spring
Data GemFire's_ Function Annotation
support|http://docs.spring.io/spring-data-gemfire/docs/current/reference/html/#function-annotations],
then they are unable to leverage other _Geode_ features as a result.
One such feature is the ability to use _Gfsh's_ '{{deploy}}' command to
(re-)deploy JAR files containing
[Function|http://gemfire.docs.pivotal.io/latest/javadocs/japi/com/gemstone/gemfire/cache/execute/Function.html]
classes "implementing" _Apache Geode_ {{Functions}} that may have been
modified and _Geode_ will "automatically" +detect+ and subsequently +register+
those updated JAR packaged {{Function(s)}}.
I have been asked, "_what is *Spring Data GemFire* going to do to support the
(hot) {{deploy}} feature?_" However, this is the +wrong+ question.
It is not what SDG can do since, technically, this is a limitation in _Geode_
(and by extension _GemFire_), and _Geode_ only detects _Geode_ specific types
(in particular, and +only+...
[com.gemstone.gemfire.cache.Function|http://gemfire.docs.pivotal.io/latest/javadocs/japi/com/gemstone/gemfire/cache/execute/Function.html]
class types). While non-{{Function}} classes and resources are technically
added to the "custom" CLASSPATH (defined by an "internal", _Geode_
{{ClassLoader}}), there is no recognition and "first-class" support for
non-_Geode_ types thereby complicating the matter for technologies that
integrate with _Geode_ such as _Spring_.
So, the right question is, "_what can _Geode_ do to recognize additional types
(or rather, meta-data annotated class types) that are not part of the core
_Geode_ types?
In essence, _Apache Goede's_ Gfsh '{{deploy}}' command needs to be enhanced to
recognize SDG-defined Function Annotated POJOs and act accordingly, in this
case.
