FreezeType

The type of network freeze or upgrade operation to be performed. This type dictates which fields are required.

Enum	Description
UNKNOWN_FREEZE_TYPE	An (invalid) default value for this enum, to ensure the client explicitly sets the intended type of freeze transaction.
FREEZE_ONLY	Freezes the network at the specified time. The start_time field must be provided and must reference a future time. Any values specified for the update_file and file_hash fields will be ignored. This transaction does not perform any network changes or upgrades and requires manual intervention to restart the network.
PREPARE_UPGRADE	A non-freezing operation that initiates network wide preparation in advance of a scheduled freeze upgrade. The update_file and file_hash fields must be provided and valid. The start_time field may be omitted and any value present will be ignored.
FREEZE_UPGRADE	Freezes the network at the specified time and performs the previously prepared automatic upgrade across the entire network.
FREEZE_ABORT	Aborts a pending network freeze operation.
TELEMETRY_UPGRADE	Performs an immediate upgrade on auxilary services and containers providing telemetry/metrics. Does not impact network operations.
