Interface SASKeyGeneratorInterface

All Known Implementing Classes:

LocalSASKeyGeneratorImpl, RemoteSASKeyGeneratorImpl, SASKeyGeneratorImpl

public interface SASKeyGeneratorInterface

Iterface used by AzureNativeFileSysteStore to retrieve SAS Keys for the respective azure storage entity. This interface is expected to be implemented in two modes: 1) Local Mode: In this mode SAS Keys are generated in same address space as the WASB. This will be primarily used for testing purposes. 2) Remote Mode: In this mode SAS Keys are generated in a sepearte process other than WASB and will be communicated via client.
