Interface LogStreamBatchReader

All Superinterfaces:

AutoCloseable, CloseableSilently, Iterator<LogStreamBatchReader.Batch>

All Known Implementing Classes:

LogStreamBatchReaderImpl

public interface LogStreamBatchReader
extends Iterator<LogStreamBatchReader.Batch>, CloseableSilently

Reads the log stream in batches. Similar to LogStreamReader but groups events with the same source event position in batches. Can be used to read all follow-up events at once.

 

 // optionally
 reader.seekToNextBatch(position);

 while (reader.hasNext()) {
     final Batch batch = reader.next();
     while (batch.hasNext()) {
         final LoggedEvent event = batch.next();
         // ...
     }
 }
