java.lang.Object

org.apache.flink.streaming.connectors.kafka.KafkaTableSource

org.apache.flink.streaming.connectors.kafka.KafkaJsonTableSource

org.apache.flink.streaming.connectors.kafka.Kafka09JsonTableSource

All Implemented Interfaces:

org.apache.flink.table.sources.DefinedFieldMapping, org.apache.flink.table.sources.DefinedProctimeAttribute, org.apache.flink.table.sources.DefinedRowtimeAttributes, org.apache.flink.table.sources.StreamTableSource<org.apache.flink.types.Row>, org.apache.flink.table.sources.TableSource<org.apache.flink.types.Row>

Deprecated.

Use the Kafka descriptor together with descriptors for schema and format instead. Descriptors allow for implementation-agnostic definition of tables. See also TableEnvironment.connect(ConnectorDescriptor).

@Deprecated
public class Kafka09JsonTableSource
extends org.apache.flink.streaming.connectors.kafka.KafkaJsonTableSource

Kafka StreamTableSource for Kafka 0.9.

                                          org.apache.flink.table.api.TableSchema tableSchema,
                                          org.apache.flink.table.api.TableSchema jsonSchema)

Deprecated. Use table descriptors instead of implementation-specific builders.

Creates a Kafka 0.9 JSON StreamTableSource.

Parameters:

topic - Kafka topic to consume.

properties - Properties for the Kafka consumer.

tableSchema - The schema of the table.

jsonSchema - The schema of the JSON messages to decode from Kafka.

Method Detail

setFailOnMissingField

@Deprecated
public void setFailOnMissingField(boolean failOnMissingField)

Deprecated. Use table descriptors instead of implementation-specific builders.

Sets the flag that specifies the behavior in case of missing fields. TableSource will fail for missing fields if set to true. If set to false, the missing field is set to null.

Overrides:

setFailOnMissingField in class org.apache.flink.streaming.connectors.kafka.KafkaJsonTableSource

Parameters:

failOnMissingField - Flag that specifies the TableSource behavior in case of missing fields.

setFieldMapping

@Deprecated
public void setFieldMapping(Map<String,String> fieldMapping)

Deprecated. Use table descriptors instead of implementation-specific builders.

Sets the mapping from table schema fields to JSON schema fields.

Overrides:

setFieldMapping in class org.apache.flink.streaming.connectors.kafka.KafkaTableSource

Parameters:

fieldMapping - The mapping from table schema fields to JSON schema fields.

setProctimeAttribute

@Deprecated
public void setProctimeAttribute(String proctimeAttribute)

Deprecated. Use table descriptors instead of implementation-specific builders.

Declares a field of the schema to be a processing time attribute.

Overrides:

setProctimeAttribute in class org.apache.flink.streaming.connectors.kafka.KafkaTableSource

Parameters:

proctimeAttribute - The name of the field that becomes the processing time field.

setRowtimeAttributeDescriptor

@Deprecated
public void setRowtimeAttributeDescriptor(org.apache.flink.table.sources.RowtimeAttributeDescriptor rowtimeAttributeDescriptor)

Deprecated. Use table descriptors instead of implementation-specific builders.

Declares a field of the schema to be a rowtime attribute.

Parameters:

rowtimeAttributeDescriptor - The descriptor of the rowtime attribute.
