    • deriveProctimeAttribute

      public static Optional<String> deriveProctimeAttribute(org.apache.flink.table.descriptors.DescriptorProperties properties)
      Deprecated.
      Finds the proctime attribute if defined.

    • deriveRowtimeAttributes

      public static List<org.apache.flink.table.legacy.sources.RowtimeAttributeDescriptor> deriveRowtimeAttributes(org.apache.flink.table.descriptors.DescriptorProperties properties)
      Deprecated.
      Finds the rowtime attributes if defined.

    • deriveTableSinkSchema

      @Deprecated public static org.apache.flink.table.legacy.api.TableSchema deriveTableSinkSchema(org.apache.flink.table.descriptors.DescriptorProperties properties)
      Deprecated.
      This method combines two separate concepts of table schema and field mapping. This should be split into two methods once we have support for the corresponding interfaces (see FLINK-9870).
      Derives the table schema for a table sink. A sink ignores a proctime attribute and needs to track the origin of a rowtime field.

    • deriveFieldMapping

      public static Map<String,String> deriveFieldMapping(org.apache.flink.table.descriptors.DescriptorProperties properties, Optional<org.apache.flink.api.common.typeinfo.TypeInformation<?>> inputType)
      Deprecated.
      Finds a table source field mapping.
      Parameters:
      properties - The properties describing a schema.
      inputType - The input type that a connector and/or format produces. This parameter can be used to resolve a rowtime field against an input field.
