Class LocalBootstrappingVeniceChangelogConsumer<K,​V>

  • Type Parameters:
    K -
    V -
    All Implemented Interfaces:
    BootstrappingVeniceChangelogConsumer<K,​V>, VeniceChangelogConsumer<K,​V>

    public class LocalBootstrappingVeniceChangelogConsumer<K,​V>
    extends VeniceAfterImageConsumerImpl<K,​V>
    This is a wrapper class on top of InternalBootstrappingVeniceChangelogConsumerImpl. This confines the usage of this class for clients to the methods exposed on the interface. This is meant to prevent users from doing seek() calls which would render the local state inconsistent.

        Description copied from interface: BootstrappingVeniceChangelogConsumer
        Start performs both a topic subscription and catch up. The client will look at the latest offset in the server and sync bootstrap data up to that point in changes. Once that is done for all partitions, the future will complete. NOTE: This future may take some time to complete depending on how much data needs to be ingested in order to catch up with the time that this client started.
        Specified by:
        start in interface BootstrappingVeniceChangelogConsumer<K,​V>
        partitions - which partition id's to catch up with
        a future that completes once catch up is complete for all passed in partitions.
