public interface SnowflakeRowSerializationSchema<T>
extends Serializable

Interface for implementing a serialization schema for serializing SnowflakeRowSerializationSchema to Map of String to Object schema as documented by the Snowflake service.

Method Summary

Modifier and Type	Method	Description
default void	open(org.apache.flink.api.common.serialization.SerializationSchema.InitializationContext initContext, SnowflakeSinkContext sinkContext)	Initialization method for the schema.
Map<String,Object>	serialize(T element, SnowflakeSinkContext sinkContext)	Serializes an element and returns it as a Map of String to Object.

Method Detail

open

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
