Method Detail

open

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

Description copied from interface: RecordSerializationSchema

Initialization method for the schema. It is called before the actual working methods RecordSerializationSchema.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.

Specified by:

open in interface RecordSerializationSchema<org.apache.flink.table.data.RowData>

Parameters:

context - Contextual information that can be used during initialization.

sinkContext - runtime information i.e. partitions, subtaskId

serialize

public StarRocksRowData serialize(org.apache.flink.table.data.RowData record)

Description copied from interface: RecordSerializationSchema

Serializes the given record and returns it as a StarRocksRowData.

Specified by:

serialize in interface RecordSerializationSchema<org.apache.flink.table.data.RowData>

Parameters:

record - element to be serialized

Returns:

a StarRocksRowData or null if the given record cannot be serialized

close

public void close()

Description copied from interface: RecordSerializationSchema

Close the serializer

Specified by:
