Example 10 with FirehoseFactory

use of org.apache.druid.data.input.FirehoseFactory in project druid by druid-io.

the class AbstractBatchIndexTask method findInputSegments.

/**
 * If the given firehoseFactory is {@link IngestSegmentFirehoseFactory}, then it finds the segments to lock
 * from the firehoseFactory. This is because those segments will be read by this task no matter what segments would be
 * filtered by intervalsToRead, so they need to be locked.
 * <p>
 * However, firehoseFactory is not IngestSegmentFirehoseFactory, it means this task will overwrite some segments
 * with data read from some input source outside of Druid. As a result, only the segments falling in intervalsToRead
 * should be locked.
 * <p>
 * The order of segments within the returned list is unspecified, but each segment is guaranteed to appear in the list
 * only once.
