While awaiting an answer to your question, may I propose a tangential question of my own: what do you think sharding is doing for you, and have you seen evidence to support this? Because DSpace uses Solr's sharding support in a very eccentric manner, and I have my doubts that it actually buys us anything. That is why I accepted the need to remove it in 7.0, in exchange for the option to place Solr on a separate host if desired (since supported Solr versions must now be installed separately anyway). The custom sharding code in DSpace doesn't get enough information to work across hosts. If sharding is really needed, Solr can do it much better on its own, and we could scrap *all* of the sharding support in DSpace.

The installation documentation mentions that sharding is no longer supported in DSpace 7, but we noticed some recent commits to the DSpace project that reference sharding and wondered if it is available again. In past versions of DSpace during solr index updates or maintenance we've sometimes struggled with slow updates or running out of memory. We have about 12 years of sharded statistics cores in DSpace 6 and are working on a strategy for importing them into DSpace 7, perhaps doing most of the exporting and importing on a separate server with solr before our upgrade day. I am curious about whether we should import all statistics into the same core for DSpace 7, as expected, or if we should keep them separated if it turns out that sharding is supported again. Can someone please help to clarify which parts of sharding are now supported, and which still do not work, and provide observations or advice?
