StarRocksRowData	serialize(T record) Serializes the given record and returns it as a StarRocksRowData.

Method Detail

open

void open(org.apache.flink.api.common.serialization.SerializationSchema.InitializationContext context,
          StarRocksSinkContext sinkContext)

Initialization method for the schema. It is called before the actual working methods serialize(Object) and thus suitable for one-time setup work.

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

Parameters:

context - Contextual information that can be used during initialization.

sinkContext - runtime information i.e. partitions, subtaskId

serialize

@Nullable
StarRocksRowData serialize(T record)

Serializes the given record and returns it as a StarRocksRowData.

Parameters:

record - element to be serialized

Returns:

a StarRocksRowData or null if the given record cannot be serialized

close

void close()

Close the serializer
