Hi there,
The action.replication_type=sync option suggests to me that *all *shards
(primary + replicas) must be written to before an index operation returns.
However, my reading of action.write_consistency suggests that it actually
dictates how many shards need to be present for a write/index to occur.
If I have the following settings:
shards: 1 primary + 2 replicas
action.replication_type: sync
action.write_consistency: quorum
What is the result? Will indexing success on the primary and a single
replica return a successful write operation to me?
Thanks very much for any help. I've included some related docs/links that
I've been through below, but have yet to be conclusive on this!
