It was designed as an extremely lightweight publish/subscribe messaging transport.</em></p> +</blockquote> + +<p>The design of Mqtt and the purpose it serves goes well together, but often in an application it is of utmost value to have reliability. Since mqtt is not a distributed message queue and thus does not offer the highest level of reliability features. It should be redirected via a kafka message queue to take advantage of a distributed message queue. In fact, using a kafka message queue offers a lot of possibilities including a single kafka topic subscribed to several mqtt sources and even a single mqtt stream publishing to multiple kafka topics. Kafka is a reliable and scalable message queue.</p> + +<ol> + <li>Often the message payload is not of the default character encoding or contains binary that needs to be parsed using a particular parser. In such cases, spark mqtt payload should be processed using the external parser. For example:</li> +</ol> + +<ul> + <li> + <p>Scala API example: +<code class="highlighter-rouge">scala + // Create DataFrame representing the stream of binary messages + val lines = spark.readStream + .format("org.apache.bahir.sql.streaming.mqtt.MQTTStreamSourceProvider") + .option("topic", topic) + .load(brokerUrl).select("payload").as[Array[Byte]].map(externalParser(_)) +</code></p> + </li> + <li> + <p>Java API example +```java + // Create DataFrame representing the stream of binary messages + Dataset<byte[]> lines = spark + .readStream() + .format(âorg.apache.bahir.sql.streaming.mqtt.MQTTStreamSourceProviderâ) + .option(âtopicâ, topic) + .load(brokerUrl).selectExpr(âCAST(payload AS BINARY)â).as(Encoders.BINARY());</p> + + <div class="highlighter-rouge"><pre class="highlight"><code> // Split the lines into words + Dataset<String> words = lines.map(new MapFunction<byte[], String>() { + @Override + public String call(byte[] bytes) throws Exception { + return new String(bytes); // Plug in external parser here. + } + }, Encoders.STRING()).flatMap(new FlatMapFunction<String, String>() { + @Override + public Iterator<String> call(String x) { + return Arrays.asList(x.split(" ")).iterator(); + } + }, Encoders.STRING()); +</code></pre> + </div> + </li> +</ul> + +<p>```</p> + +<ol> + <li>What is the solution for a situation when there are a large number of varied mqtt sources, each with different schema and throughput characteristics.</li> +</ol> + +<p>Generally, one would create a lot of streaming pipelines to solve this problem. This would either require a very sophisticated scheduling setup or will waste a lot of resources, as it is not certain which stream is using more amount of data.</p> + +<p>The general solution is both less optimum and is more cumbersome to operate, with multiple moving parts incurs a high maintenance overall. As an alternative, in this situation, one can setup a single topic kafka-spark stream, where message from each of the varied stream contains a unique tag separating one from other streams. This way at the processing end, one can distinguish the message from one another and apply the right kind of decoding and processing. Similarly while storing, each message can be distinguished from others by a tag that distinguishes.</p> </div> http://git-wip-us.apache.org/repos/asf/bahir-website/blob/f7e05e11/content/docs/spark/current/spark-streaming-pubnub/index.html ---------------------------------------------------------------------- diff --git a/content/docs/spark/current/spark-streaming-pubnub/index.html b/content/docs/spark/current/spark-streaming-pubnub/index.html new file mode 100644 index 0000000..37083fd --- /dev/null +++ b/content/docs/spark/current/spark-streaming-pubnub/index.html @@ -0,0 +1,338 @@ + + +<!DOCTYPE html> +<html lang="en"> + <head> + <meta charset="utf-8"> + <title>Spark Streaming Google Pub-Sub</title> + <meta name="description" content="Spark Streaming Google Pub-Sub"> + <meta name="author" content=""> + + <!-- Enable responsive viewport --> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + + <!-- Le HTML5 shim, for IE6-8 support of HTML elements --> + <!--[if lt IE 9]> + <script src="http://html5shim.googlecode.com/svn/trunk/html5.js";></script> + <![endif]--> + + <!-- Le styles --> + <link href="/assets/themes/apache-clean/bootstrap/css/bootstrap.css" rel="stylesheet"> + <link href="/assets/themes/apache-clean/css/style.css?body=1" rel="stylesheet" type="text/css"> + <link href="/assets/themes/apache-clean/css/syntax.css" rel="stylesheet" type="text/css" media="screen" /> + <!-- Le fav and touch icons --> + <!-- Update these with your own images + <link rel="shortcut icon" href="images/favicon.ico"> + <link rel="apple-touch-icon" href="images/apple-touch-icon.png"> + <link rel="apple-touch-icon" sizes="72x72" href="images/apple-touch-icon-72x72.png"> + <link rel="apple-touch-icon" sizes="114x114" href="images/apple-touch-icon-114x114.png"> + --> + + <!-- make tables sortable by adding class tag "sortable" to table elements --> + <script src="http://www.kryogenix.org/code/browser/sorttable/sorttable.js";></script> + + + </head> + + <body> + + + +<!-- Navigation --> +<div id="nav-bar"> + <nav id="nav-container" class="navbar navbar-inverse " role="navigation"> + <div class="container"> + <!-- Brand and toggle get grouped for better mobile display --> + + <div class="navbar-header page-scroll"> + <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"> + <span class="sr-only">Toggle navigation</span> + <span class="icon-bar"></span> + <span class="icon-bar"></span> + <span class="icon-bar"></span> + </button> + <a class="navbar-brand page-scroll" href="/#home">Home</a> + </div> + <!-- Collect the nav links, forms, and other content for toggling --> + <nav class="navbar-collapse collapse" role="navigation"> + <ul class="nav navbar-nav"> + + + + <li id="download"> + + <a href="#" data-toggle="dropdown" class="dropdown-toggle">Download<b class="caret"></b></a> + <ul class="dropdown-menu dropdown-left"> + + + <li><a href="/downloads/spark" target="_self">Bahir Spark Extensions</a></li> + + + <li><a href="/downloads/flink" target="_self">Bahir Flink Extensions</a></li> + + </ul> + + </li> + + + + + <li id="community"> + + <a href="#" data-toggle="dropdown" class="dropdown-toggle">Community<b class="caret"></b></a> + <ul class="dropdown-menu dropdown-left"> + + + <li><a href="/community" target="_self">Get Involved</a></li> + + + <li><a href="/contributing" target="_self">Contributing</a></li> + + + <li><a href="/contributing-extensions" target="_self">Contributing Extensions</a></li> + + + <li><a href="https://issues.apache.org/jira/browse/BAHIR";
