dropStoragePartitionGracefully

default void dropStoragePartitionGracefully(VeniceStoreVersionConfig storeConfig,
                                            int partition,
                                            int timeoutInSeconds)

This method stops to subscribe the specified topic partition and delete partition data from storage and it will always drop empty storage engine.

Parameters:

storeConfig - Store version config

partition - Partition number to be dropped in the store version.

timeoutInSeconds - Number of seconds to wait before timeout.

dropStoragePartitionGracefully

void dropStoragePartitionGracefully(VeniceStoreVersionConfig storeConfig,
                                    int partition,
                                    int timeoutInSeconds,
                                    boolean removeEmptyStorageEngine)

This method stops to subscribe the specified topic partition and delete partition data from storage.

Parameters:

storeConfig - Store version config

partition - Partition number to be dropped in the store version.

timeoutInSeconds - Number of seconds to wait before timeout.

removeEmptyStorageEngine - Whether to drop storage engine when dropping the last partition.

getStoreIngestionService

KafkaStoreIngestionService getStoreIngestionService()

removeStorageEngine

void removeStorageEngine(java.lang.String topicName)

setStorageEngineReference
