Deprecated Classes

Class and Description
org.apache.flink.table.util.TableConnectorUtil Use TableConnectorUtils instead.
org.apache.flink.table.typeutils.TimeIndicatorTypeInfo This class will be removed in future versions as it is used for the old type system. It is recommended to use DataTypes instead. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.typeutils.TimeIntervalTypeInfo This class will be removed in future versions as it is used for the old type system. It is recommended to use DataTypes instead. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.api.Types This class will be removed in future versions as it uses the old type system. It is recommended to use DataTypes instead which uses the new type system based on instances of DataType. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.utils.TypeStringUtils This utility is based on TypeInformation. However, the Table & SQL API is currently updated to use DataTypes based on LogicalTypes. Use LogicalTypeParser instead.

Deprecated Fields

Field and Description
org.apache.flink.table.descriptors.Schema.SCHEMA_TYPE Schema uses the legacy type key (e.g. schema.0.type = LONG) to store type information in prior v1.9. Since v1.10, Schema uses data type key (e.g. schema.0.data-type = BIGINT) to store types.
org.apache.flink.table.descriptors.DescriptorProperties.TABLE_SCHEMA_TYPE this will be removed in future version as it uses old type system. Please use DescriptorProperties.TABLE_SCHEMA_DATA_TYPE instead.

Deprecated Methods

Method and Description
org.apache.flink.table.api.DataTypes.ANY(Class<T>, TypeSerializer<T>) Use DataTypes.RAW(Class, TypeSerializer) instead.
org.apache.flink.table.api.DataTypes.ANY(TypeInformation<T>) Use DataTypes.RAW(TypeInformation) instead.
org.apache.flink.table.sinks.TableSink.configure(String[], TypeInformation<?>[]) This method will be dropped in future versions. It is recommended to pass a static schema when instantiating the sink instead.
org.apache.flink.table.descriptors.Schema.field(String, TypeInformation<?>) This method will be removed in future versions as it uses the old type system. Please use Schema.field(String, DataType) instead.
org.apache.flink.table.api.TableSchema.Builder.field(String, TypeInformation<?>) This method will be removed in future versions as it uses the old type system. It is recommended to use TableSchema.Builder.field(String, DataType) instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.api.TableSchema.fromTypeInfo(TypeInformation<?>) This method will be removed soon. Use DataTypes to declare types.
org.apache.flink.table.sinks.TableSink.getFieldNames() Use the field names of TableSink.getTableSchema() instead.
org.apache.flink.table.api.TableSchema.getFieldType(int) This method will be removed in future versions as it uses the old type system. It is recommended to use TableSchema.getFieldDataType(int) instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.api.TableSchema.getFieldType(String) This method will be removed in future versions as it uses the old type system. It is recommended to use TableSchema.getFieldDataType(String) instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.sinks.TableSink.getFieldTypes() Use the field types of TableSink.getTableSchema() instead.
org.apache.flink.table.api.TableSchema.getFieldTypes() This method will be removed in future versions as it uses the old type system. It is recommended to use TableSchema.getFieldDataTypes() instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.plan.stats.ColumnStats.getMaxValue()
org.apache.flink.table.plan.stats.ColumnStats.getMinValue()
org.apache.flink.table.sinks.TableSink.getOutputType() This method will be removed in future versions as it uses the old type system. It is recommended to use TableSink.getConsumedDataType() instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.sources.TableSource.getReturnType() This method will be removed in future versions as it uses the old type system. It is recommended to use TableSource.getProducedDataType() instead which uses the new type system based on DataTypes. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.
org.apache.flink.table.sources.TableSource.getTableSchema() Table schema is a logical description of a table and should not be part of the physical TableSource. Define schema when registering a Table either in DDL or in TableEnvironment#connect(...).
org.apache.flink.table.functions.AggregateFunction.requiresOver() Use AggregateFunction.getRequirements() instead.
org.apache.flink.table.api.TableSchema.toRowType() Use TableSchema.toRowDataType() instead.

Deprecated Constructors

Constructor and Description
org.apache.flink.table.plan.stats.ColumnStats(Long, Long, Double, Integer, Number, Number)
org.apache.flink.table.api.TableSchema(String[], TypeInformation<?>[]) Use the TableSchema.Builder instead.
