I’m reading through the Replication Zone documentation, and am a bit confused by the zone config format semantics. Specifically in the attributes declarations for zone configurations. All the examples use 3 attributes, and this seems to make sense for the availability zone examples (replicate across us-west-1a, us-east-1a, etc), but the SSD example throws me off:
replicas: - attrs: [ssd] - attrs: [ssd] - attrs: [ssd]
Is there a need for
ssd to be stated as an attribute 3 times? Moreover, is there some magic in having 3 replica attributes? Is it possible to list more than 3 attributes?
Also, small housekeeping note, the examples on that page for starting nodes with store attributes don’t work. They all declare the store as
--store=path=node1-data,attr=ssd, but it should be
