I am trying to implement Chronicle Queue into our system and had a question regarding rolling of files daily but at a specific time as per the local time zone of the process. I read few write-ups regarding how to specify roll cycle but as per documentation the epoch time works as per midnight UTC. What would I need to do to configure a roll cycle let's say every day at 5PM local time zone of the process running? Any suggestions?
public class TestRollCycle {
public class TestClass implements TestEvent {
private int counter = 1;
@Override
public void setOrGetEvent(String event) {
System.out.println("Counter Read Value: " + counter);
counter++;
}
}
public interface TestEvent {
void setOrGetEvent(String event);
}
@Test
public void testRollProducer() {
int insertCount = 1;
String pathOfFile = "rollPath";
// Epoch is 5:15PM EDT
SingleChronicleQueue producerQueue = SingleChronicleQueueBuilder.binary(pathOfFile).epoch(32940000).build();
ExcerptAppender myAppender = producerQueue.acquireAppender();
TestEvent eventWriter = myAppender.methodWriter(TestEvent.class);
while (true) {
String testString = "Insert String";
eventWriter.setOrGetEvent(testString);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Counter Write Value: " + insertCount);
insertCount++;
}
}
@Test
public void testRollConsumer() throws InterruptedException {
String pathOfFile = "rollPath";
// Epoch is 5:15PM EDT
SingleChronicleQueue producerQueue = SingleChronicleQueueBuilder.binary(pathOfFile).epoch(32940000).build();
TestClass myClass = new TestClass();
ExcerptTailer trailer = producerQueue.createTailer();
MethodReader methodReader = trailer.methodReader(myClass);
while (true) {
if (!methodReader.readOne()) {
Thread.sleep(1000);
} else {
//System.out.println(trailer.index());
}
}
}
}
