      void deleteStore(String clusterName, String storeName, int largestUsedVersionNumber, boolean waitOnRTTopicDeletion)
      Delete the entire store including both metadata and real user's data. Before deleting a store, we should disable the store manually to ensure there is no reading/writing request hitting this tore.

    • addVersionAndStartIngestion

    • incrementVersionIdempotent

      default Version incrementVersionIdempotent(String clusterName, String storeName, String pushJobId, int numberOfPartitions, int replicationFactor)
      The implementation of this method must take no action and return the same Version object if the same parameters are provided on a subsequent invocation. The expected use is multiple distributed components of a single push (with a single jobPushId) that each need to query Venice for the Version (and Kafka topic) to write into. The first task triggers a new Version, all subsequent tasks identify with the same jobPushId, and should be provided with the same Version object.
