This description is taken verbatim from the CSI Spec: A topological domain is a sub-division of a cluster, like "region", "zone", "rack", etc. A topological segment is a specific instance of a topological domain, like "zone3", "rack3", etc. For example {"com.company/zone": "Z1", "com.company/rack": "R3"} 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.
