This documentation is for version 1 of the Amazon Kinesis Data Analytics API, which only supports SQL applications. Version 2 of the API supports SQL and Java applications. For more information about version 2, see Amazon Kinesis Data Analytics API V2 Documentation.
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 three 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.
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 three 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.
For introductory exercises to create an Amazon Kinesis Analytics application, see Getting Started.

Creating a Request
data CreateApplication Source #
TBD
See: newCreateApplication
smart constructor.
CreateApplication' | |
|
Instances
Create a value of CreateApplication
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:applicationDescription:CreateApplication'
, createApplication_applicationDescription
- Summary description of the application.
$sel:inputs:CreateApplication'
, createApplication_inputs
- 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).
For the streaming source, you provide its Amazon Resource Name (ARN) and format of data on the stream (for example, JSON, CSV, etc.). You also must provide an IAM role that Amazon Kinesis Analytics can assume to read this stream on your behalf.
To create the in-application stream, you need to specify a schema to transform your data into a schematized version used in SQL. In the schema, you provide the necessary mapping of the data elements in the streaming source to record columns in the in-app stream.
$sel:cloudWatchLoggingOptions:CreateApplication'
, createApplication_cloudWatchLoggingOptions
- Use this parameter to configure a CloudWatch log stream to monitor
application configuration errors. For more information, see
Working with Amazon CloudWatch Logs.
$sel:outputs:CreateApplication'
, createApplication_outputs
- You can configure application output to write data from any of the
in-application streams to up to three destinations.
These destinations can be Amazon Kinesis streams, Amazon Kinesis Firehose delivery streams, AWS Lambda destinations, or any combination of the three.
In the configuration, you specify the in-application stream name, the destination stream or Lambda function Amazon Resource Name (ARN), and the format to use when writing data. You must also provide an IAM role that Amazon Kinesis Analytics can assume to write to the destination stream or Lambda function on your behalf.
In the output configuration, you also provide the output stream or Lambda function ARN. For stream destinations, you provide the format of data in the stream (for example, JSON, CSV). You also must provide an IAM role that Amazon Kinesis Analytics can assume to write to the stream or Lambda function on your behalf.
$sel:applicationCode:CreateApplication'
, createApplication_applicationCode
- One or more SQL statements that read input data, transform it, and
generate output. For example, you can write a SQL statement that reads
data from one in-application stream, generates a running average of the
number of advertisement clicks by vendor, and insert resulting rows in
another in-application stream using pumps. For more information about
the typical pattern, see
Application Code.
You can provide such series of SQL statements, where output of one statement can be used as the input for the next statement. You store intermediate results by creating in-application streams and pumps.
Note that the application code must create the streams with names
specified in the Outputs
. For example, if your Outputs
defines
output streams named ExampleOutputStream1
and ExampleOutputStream2
,
then your application code must create these streams.
$sel:tags:CreateApplication'
, createApplication_tags
- A list of one or more tags to assign to the application. A tag is a
key-value pair that identifies an application. Note that the maximum
number of application tags includes system tags. The maximum number of
user-defined application tags is 50. For more information, see
Using Tagging.
$sel:applicationName:CreateApplication'
, createApplication_applicationName
- Name of your Amazon Kinesis Analytics application (for example,
sample-app
).
