Amazon Kinesis Data Analytics
Developer Guide

Step 1: Prepare the Data

In this section, you create a Kinesis data stream, and then populate order and trade records on the stream. This is your streaming source for the application that you create in the next step.

Step 1.1: Create a Streaming Source

You can create a Kinesis data stream using the console or the AWS CLI. The example assumes OrdersAndTradesStream as the stream name.

  • Using the console – Sign in to the AWS Management Console and open the Kinesis console at Choose Data Streams, and then create a stream with one shard. For more information, see Create a Stream in the Amazon Kinesis Data Streams Developer Guide.

  • Using the AWS CLI – Use the following Kinesis create-stream AWS CLI command to create the stream:

    $ aws kinesis create-stream \ --stream-name OrdersAndTradesStream \ --shard-count 1 \ --region us-east-1 \ --profile adminuser

Step 1.2: Populate the Streaming Source

Run the following Python script to populate sample records on the OrdersAndTradesStream. If you created the stream with a different name, update the Python code appropriately.

  1. Install Python and pip.

    For information about installing Python, see the Python website.

    You can install dependencies using pip. For information about installing pip, see Installation on the pip website.

  2. Run the following Python code. The put-record command in the code writes the JSON records to the stream.

    import testdata import json from boto import kinesis import random kinesis = kinesis.connect_to_region("us-east-1") def getOrderData(orderId, ticker): data = {} data['RecordType'] = "Order" data['Oid'] = orderId data['Oticker'] = ticker data['Oprice'] = random.randint(500, 10000) data['Otype'] = "Sell" return data def getTradeData(orderId, tradeId, ticker, tradePrice): data = {} data['RecordType'] = "Trade" data['Tid'] = tradeId data['Toid'] = orderId data['Tticker'] = ticker data['Tprice'] = tradePrice return data x = 1 while True: #rnd = random.random() rnd = random.randint(1,3) if rnd == 1: ticker = "AAAA" elif rnd == 2: ticker = "BBBB" else: ticker = "CCCC" data = json.dumps(getOrderData(x, ticker)) kinesis.put_record("OrdersAndTradesStream", data, "partitionkey") print data tId = 1 for y in range (0, random.randint(0,6)): tradeId = tId tradePrice = random.randint(0, 3000) data2 = json.dumps(getTradeData(x, tradeId, ticker, tradePrice)); kinesis.put_record("OrdersAndTradesStream", data2, "partitionkey") print data2 tId+=1 x+=1
