Class HoodieActiveTimeline

java.lang.Object

org.apache.hudi.common.table.timeline.HoodieDefaultTimeline

org.apache.hudi.common.table.timeline.HoodieActiveTimeline

All Implemented Interfaces:

Serializable, HoodieTimeline

public class HoodieActiveTimeline
extends HoodieDefaultTimeline

Represents the Active Timeline for the Hoodie table. Instants for the last 12 hours (configurable) is in the ActiveTimeline and the rest are Archived. ActiveTimeline is a special timeline that allows for creation of instants on the timeline.

The timeline is not automatically reloaded on any mutation operation, clients have to manually call reload() so that they can chain multiple mutations to the timeline and then call reload() once.

This class can be serialized and de-serialized and on de-serialization the FileSystem is re-initialized.
