Xapiand Glossary Missing!

I've been poking around again. This time I was trying to grok what capabilities xapiand has for syncing data between systems. Despite reading what documentation is written around this subject, I still am extremely foggy in understanding.

Story Time

I fired up three instances like this:

# 1st
# pwd: xapiand-test
xapiand -vvvv --name=Cthulhu --cluster=fuck --database=db

# 2nd
# pwd: xapiand-test/GibberingMouther
xapiand -vvvv --name=GibberingMouther --cluster=fuck --database=db

# 3rd
# pwd: xapiand-test/EldritchEffulgence
xapiand -vvvv --name=EldritchEffulgence --cluster=fuck --database=db

All that seems to work flawlessly as far as I can tell. The data seems to sync between the 3 nodes. I am confused, though, about scenarios when nodes go offline.

If I have two instances, one local, one in a remote data center, will they replicate/sync?

Finally, can I get a quick description of the following terms and their relations to each other?

• Clusters
• Nodes
• Shards
• Replication
• Leaders
