Values.DiscoverInputSchemaResponseSourceInfers a schema for a SQL-based Kinesis Data Analytics application by evaluating sample records on the specified streaming source (Kinesis data stream or Kinesis Data Firehose delivery stream) or Amazon S3 object. In the response, the operation returns the inferred schema and also the sample records that the operation used to infer the schema. You can use the inferred schema when configuring a streaming source for your application. When you create an application using the Kinesis Data Analytics console, the console uses this operation to infer a schema and show it in the console user interface.
type nonrec t = {inputSchema : SourceSchema.t option;The schema inferred from the streaming source. It identifies the format of the data in the streaming source and how each data element maps to corresponding columns in the in-application stream that you can create.
*)parsedInputRecords : ParsedInputRecords.t option;An array of elements, where each element corresponds to a row in a stream record (a stream record can have more than one row).
*)processedInputRecords : ProcessedInputRecords.t option;The stream data that was modified by the processor specified in the InputProcessingConfiguration parameter.
*)rawInputRecords : RawInputRecords.t option;The raw stream data that was sampled to infer the schema.
