Himanshu Gahlaut updated LENS-678:
----------------------------------
Description:
https://github.com/apache/incubator-lens/blob/master/lens-server/src/test/resources/lens-site.xml#L122
{code:xml}
<property>
<!-- Immediately insert all finished queries to DB -->
<name>lens.server.max.finished.queries</name>
<value>1</value>
</property>
{code}
Comment mentions that finished queries will be immediately inserted into DB.
As per code given below, for a finished query to be immediately inserted into
DB, (size > maxFinishedQueries) expression should be true. Assume one query
enters finishedQueries queue. (size = 1). To immediately deque this query, 1
should be greater than maxFinishedQueries. This would happen only if
maxFinishedQueries is 0. However in the lens-site.xml code above,
lens.server.max.finished.queries is set to 1.
{code}
@Override
public long getDelay(TimeUnit units) {
int size = finishedQueries.size();
if (size > maxFinishedQueries) {
return 0;
} else {
return Integer.MAX_VALUE;
}
}
{code}
