io.datarouter.filesystem.snapshot.reader.block.ScanningBlockReader

public class ScanningBlockReader
extends Object

Thread-safe The parallel operations perform the potentially high-latency block fetches The blocks are passed to the parent scanner which parses them. The parsing could potentially be done in the parallel section, but it would result in more objects being allocated at the same time. The parsing of the blocks is pretty inexpensive, so this version leaves that for the parent reader thread.
