type CSITopology added in v0.11.0 

type CSITopology struct {
	Segments map[string]string
}

CSITopology is a map of topological domains to topological segments. A topological domain is a sub-division of a cluster, like "region", "zone", "rack", etc.

According to CSI, there are a few requirements for the keys within this map: - Valid keys have two segments: an OPTIONAL prefix and name, separated 

by a slash (/), for example: "com.company.example/zone".

- The key name segment is REQUIRED. The prefix is OPTIONAL. - The key name MUST be 63 characters or less, begin and end with an 

alphanumeric character ([a-z0-9A-Z]), and contain only dashes (-),
underscores (_), dots (.), or alphanumerics in between, for example
"zone".

- The key prefix MUST be 63 characters or less, begin and end with a 

lower-case alphanumeric character ([a-z0-9]), contain only
dashes (-), dots (.), or lower-case alphanumerics in between, and
follow domain name notation format
(https://tools.ietf.org/html/rfc1035#section-2.3.1).

- The key prefix SHOULD include the plugin's host company name and/or 

the plugin name, to minimize the possibility of collisions with keys
from other plugins.

- If a key prefix is specified, it MUST be identical across all 

topology keys returned by the SP (across all RPCs).

- Keys MUST be case-insensitive. Meaning the keys "Zone" and "zone" 

MUST not both exist.

- Each value (topological segment) MUST contain 1 or more strings. - Each string MUST be 63 characters or less and begin and end with an 

alphanumeric character with '-', '_', '.', or alphanumerics in
between.

However, Nomad applies lighter restrictions to these, as they are already only referenced by plugin within the scheduler and as such collisions and related concerns are less of an issue. We may implement these restrictions in the future.
