2016/08/11 - Amazon Kinesis Analytics - 13 new api methods
Changes Adds the new service Amazon Kinesis Analytics, a fully managed service for continuously querying streaming data using standard SQL. With Kinesis Analytics, you can write standard SQL queries on streaming data and gain actionable insights in real-time, without having to learn any new programming skills. The service allows you to build applications that continuously read data from streaming data sources, process that data using standard SQL, and send the processed data to up to four destinations of your choice. Kinesis Analytics enables you to generate time-series analytics, feed a real-time dashboard, create real-time alarms and notifications, and much more.
Infers a schema by evaluating sample records on the specified streaming source (Amazon Kinesis stream or Amazon Kinesis Firehose delivery stream). 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. For conceptual information, see Configuring Application Input . Note that when you create an application using the Amazon Kinesis Analytics console, the console uses this operation to infer a schema and show it in the console user interface.
This operation requires permissions to perform the kinesisanalytics:DiscoverInputSchema action.

Creates an Amazon Kinesis Analytics application. You can configure each application with one streaming source as input, application code to process the input, and up to five streaming destinations where you want Amazon Kinesis Analytics to write the output data from your application. For an overview, see How it Works .
In the input configuration, you map the streaming source to an in-application stream, which you can think of as a constantly updating table. In the mapping, you must provide a schema for the in-application stream and map each data column in the in-application stream to a data element in the streaming source, with the option of renaming, casting and dropping columns as desired.
Your application code is one or more SQL statements that read input data, transform it, and generate output. Your application code can create one or more SQL artifacts like SQL streams or pumps.
In the output configuration, you can configure the application to write data from in-application streams created in your applications to up to five streaming destinations.
To read data from your source stream or write data to destination streams, Amazon Kinesis Analytics needs your permissions. You grant these permissions by creating IAM roles. This operation requires permissions to perform the kinesisanalytics:CreateApplication action.

Use this parameter to configure the application input.
You can configure your application to receive input from a single streaming source. In this configuration, you map this streaming source to an in-application stream that is created. Your application code can then query the in-application stream like a table (you can think of it as a constantly updating table).
