Thanks to Claudio and Matthew, I went with the WorkerContext solution. Note
that I wrote a MasterCompute.validate() to verify the correct WorkerContext
class was set. Otherwise I was worried my cast would fail. -- matt

I would use a workercontext, it is shared and persistent during
computation by all vertices in a worker. If it's readonly, you won't have
to manage concurrency.

Hi Folks. I have a custom argument that's passed into my Giraph job that
needs parsing. The parsed value is accessed by my Vertex#compute. To avoid
excessive GC I'd like to cache the parsing results. What's a good way to do
so? I looked at using the ImmutableClassesGiraphConfiguration returned by
getConf(), but it supports only String properties. I looked at using my
custom MasterCompute to manage it, but I couldn't find how to access the
master compute instance from the vertex. My last idea is to use (abuse?) an
aggregator to do this. I'd appreciate your thoughts! -- matt
