Method Detail

consumeDataStream

public DataStreamSink<?> consumeDataStream(DataStream<Tuple2<Boolean,Row>> dataStream)

Description copied from interface: StreamTableSink

Consumes the DataStream and return the sink transformation DataStreamSink. The returned DataStreamSink will be used to set resources for the sink operator.

Specified by:

consumeDataStream in interface StreamTableSink<Tuple2<Boolean,Row>>

setKeyFields

public void setKeyFields(String[] keys)

Description copied from interface: UpsertStreamTableSink

Configures the unique key fields of the Table to write. The method is called after TableSink.configure(String[], TypeInformation[]).

The keys array might be empty, if the table consists of a single (updated) record. If the table does not have a key and is append-only, the keys attribute is null.

Specified by:

setKeyFields in interface UpsertStreamTableSink<Row>

Parameters:

keys - the field names of the table's keys, an empty array if the table has a single row, and null if the table is append-only and has no key.

setIsAppendOnly

public void setIsAppendOnly(Boolean isAppendOnly)

Description copied from interface: UpsertStreamTableSink

Specifies whether the Table to write is append-only or not.

Specified by:

setIsAppendOnly in interface UpsertStreamTableSink<Row>

Parameters:

isAppendOnly - true if the table is append-only, false otherwise.

getOutputType

public TypeInformation<Tuple2<Boolean,Row>> getOutputType()

Specified by:

getOutputType in interface TableSink<Tuple2<Boolean,Row>>

Specified by:

getOutputType in interface UpsertStreamTableSink<Row>

getRecordType

public TypeInformation<Row> getRecordType()

Description copied from interface: UpsertStreamTableSink

Returns the requested record type.

Specified by:

getRecordType in interface UpsertStreamTableSink<Row>

getFieldNames

public String[] getFieldNames()

Specified by:

getFieldNames in interface TableSink<Tuple2<Boolean,Row>>

getFieldTypes

public TypeInformation<?>[] getFieldTypes()

Specified by:

configure

public TableSink<Tuple2<Boolean,Row>> configure(String[] fieldNames,
                                                TypeInformation<?>[] fieldTypes)

Description copied from interface: TableSink

Returns a copy of this TableSink configured with the field names and types of the table to emit.

Specified by:

configure in interface TableSink<Tuple2<Boolean,Row>>

Parameters:

fieldNames - The field names of the table to emit.

fieldTypes - The field types of the table to emit.

Returns:
