Class DruidServer

java.lang.Object

org.apache.druid.client.DruidServer

All Implemented Interfaces:

Comparable<DruidServer>

public class DruidServer
extends Object
implements Comparable<DruidServer>

A mutable collection of metadata of segments (DataSegment objects), stored on a particular Druid server (typically historical). This class should not be subclassed, it isn't declared final only to make it possible to mock the class with EasyMock in tests.

See Also:

• - an immutable counterpart of this class

iterateAllSegments

public Iterable<DataSegment> iterateAllSegments()

Returns an iterable to go over all segments in all data sources, stored on this DruidServer. The order in which segments are iterated is unspecified. Since this DruidServer can be mutated concurrently, the set of segments observed during an iteration may _not_ be a momentary snapshot of the segments on the server, in other words, it may be that there was no moment when the DruidServer stored exactly the returned set of segments. Note: the iteration may not be as trivially cheap as, for example, iteration over an ArrayList. Try (to some reasonable extent) to organize the code so that it iterates the returned iterable only once rather than several times.

getTotalSegments

public int getTotalSegments()

Returns the current number of segments, stored in this DruidServer object. This number if weakly consistent with the number of segments if iterateAllSegments() is iterated about the same time, because segments might be added or removed in parallel.

getSegment
