KnownZonalAllocationPolicy enum
Optional: Specifies how availability zones are allocated to the Redis cache. 'Automatic' enables zone redundancy and Azure will automatically select zones based on regional availability and capacity. 'UserDefined' will select availability zones passed in by you using the 'zones' parameter. 'NoZones' will produce a non-zonal cache. If 'zonalAllocationPolicy' is not passed, it will be set to 'UserDefined' when zones are passed in, otherwise, it will be set to 'Automatic' in regions where zones are supported and 'NoZones' in regions where zones are not supported.
Fields
| Automatic | The zones for the cache will be selected automatically based on availability and capacity. |
| NoZones | The cache will not use multiple availability zones. |
| UserDefined | UserDefined means the zones for the cache are manually configured using the 'zones' property, and can not be automatically selected. |
