Method Detail

startConsumption

void startConsumption(VeniceStoreVersionConfig veniceStore,
                      int partitionId)

Starts consuming messages from Kafka Partition corresponding to Venice Partition.

Parameters:

veniceStore - Venice Store for the partition.

partitionId - Venice partition's id.

stopConsumption

java.util.concurrent.CompletableFuture<java.lang.Void> stopConsumption(VeniceStoreVersionConfig veniceStore,
                                                                       int partitionId)

Stops consuming messages from Kafka Partition corresponding to Venice Partition.

Parameters:

veniceStore - Venice Store for the partition.

partitionId - Venice partition's id.

stopConsumptionAndWait

void stopConsumptionAndWait(VeniceStoreVersionConfig veniceStore,
                            int partitionId,
                            int sleepSeconds,
