> Do you have any advise for someone thinking of deploying on GCE?
No, sorry, I've never used that. However, generally - like all dbs, Orient is happiest when it has access to a lot of RAM. Also the Write Ahead Log can take up a significant amount of disk space, those are two things to be immediately aware of.
> I'm also interested in understanding if there is any built-in compression mechanism because I will be storing a large volume of very similar text files. Any hints?
Sadly it doesn't yet do leveldb style document compression, and I've seen no hints that it's on the horizon, but the OrientDB guys are pretty responsive and would probably be open to the suggestion.
> Have you used the lucene indexes much? If so, can you do any of the crazy faceting delivered by ElasticSearch?
I'm just starting to use the lucene indexes now so I can't give much feedback on those yet. It should be possible to do faceting using SQL to a limited degree, but I don't think there's native support for it yet. I think that will get improved in the next few versions because people are crying out for it.
