dataformat

const (
	// PreviousFormat specifies the data format in previous fabric version
	PreviousFormat = ""

	// CurrentFormat specifies the data format in current fabric version
	CurrentFormat = "2.0"
)

The data format stored in ledger databases may be changed in a new release to support new features. This file defines the constants to check whether or not the data format on the ledger matches the CurrentFormat. If not matched, peer start will fail and the ledger must be upgraded to the CurrentFormat. If a Fabric version does not introduce a new data format, CurrentFormat will remain the same as the latest format prior to the Fabric version.
