  • Method Details

    • getStorageEngine

      public abstract StorageEngine getStorageEngine(VeniceStoreVersionConfig storeDef) throws StorageInitializationException
      Get an initialized storage implementation
      Parameters:
      storeDef - store definition
      Returns:
      The storage engine
      Throws:
      StorageInitializationException

    • getStorageEngine

      public StorageEngine getStorageEngine(VeniceStoreVersionConfig storeDef, boolean replicationMetadataEnabled)
      Replication metadata is only supported in RocksDB storage engine. For other type of the storage engine, we will throw VeniceException here.

      public abstract Set<String> getPersistedStoreNames()
      Retrieve all the stores persisted previously
      Returns:
      All the store names

    • close

      public abstract void close()
      Close the storage configuration

    • removeStorageEngine

      public abstract void removeStorageEngine(StorageEngine engine)
      Remove the storage engine from the underlying storage configuration
      Parameters:
      engine - Specifies the storage engine to be removed
