Class ChunkingStorageConnectorParameters<T>

java.lang.Object

org.apache.druid.storage.remote.ChunkingStorageConnectorParameters<T>

public class ChunkingStorageConnectorParameters<T>
extends Object

POJO for storing the parameters required to support chunking of the downloads by ChunkingStorageConnector. The implementations of the ChunkingStorageConnector should essentially provide a way to build this object, which contains the information required to support chunking. Therefore, to a call of StorageConnector.readRange(String, long, long), the implementations of the chunking storage connectors would fetch the required chunks using the information present in this POJO.
