Hi Bjoern,

Thank you for the prompt reply!

I didn't know what to look for, but now that you mention it, I can
search for "ObjectStore" in the configuration file...  Looking at
object_store_conf.xml.sample, it looks like I can specify various
partitions and when data is stored.  I presume when it comes time to
store the data, the location is determined and some look-up table is
updated?

That's indeed what I was looking for!  Is "object store" in Galaxy's
documentation not the same as "ObjectStore"?  I just searched for this
term on Google and it seems to be a commercial database
[https://en.wikipedia.org/wiki/ObjectStore].

Thank you for the offer to send me your configuration!  Let me play
around with it a bit and see how hard it is, first...

Thanks!

Ray
