      default void open(org.apache.flink.api.common.serialization.SerializationSchema.InitializationContext initContext, SnowflakeSinkContext sinkContext) throws Exception
      Initialization method for the schema. It is called before serialize(Object, SnowflakeSinkContext), hence, suitable for one time setup work.

      The provided SerializationSchema.InitializationContext can be used to access additional features such as registering user metrics.

      Parameters:
      initContext - SerializationSchema.InitializationContext Contextual information for initialization
      sinkContext - SnowflakeSinkContext Runtime context
      Throws:
      Exception

    • serialize

      Map<String,Object> serialize(T element, SnowflakeSinkContext sinkContext)
      Serializes an element and returns it as a Map of String to Object.
      Parameters:
      element - generically typed element to be serialized
      sinkContext - Runtime context, e.g. subtask ID, etc.
      Returns:
      Map of String to Object
