> FunctionContext has methods to get the arguments to the function and the result sender,
but there is no way to get the Cache or DistributedSystem.
> This means pretty much any function will need to statically look up the cache using CacheFactory.getAnyInstance().
While that works, it makes it impossible to write unit tests for functions by passing in a
mock cache.
> Note that onRegion functions are provided a RegionFunctionContext, which does provide
these functions with a means to look up the cache, but not all functions are applied to a
region.
