Purpose of "computer" section in MySQL Cluster 7.2?
- by dpk
According to the cluster documentation, you can either define data nodes with:
[ndbd]
NodeId=n
HostName=1.2.3.4
or
[ndbd]
NodeId=n
ExecuteOnComputer=m
[computer]
Id=m
HostName=1.2.3.4
I don't see a substantial difference between the two. The documentation has this to say:
The [computer] section has no real significance other than serving as
a way to avoid the need of defining host names for each node in the
system.
I'm stumped. If I have to define a hostname, what benefit is there to defining it in [computer] instead of [ndbd]?
