JAZOON'13 - Kai Waehner - Hadoop Integration

J
jazoon13

This document discusses integrating big data beyond Hadoop. It begins with an introduction and overview of Kai Wähner and his background and expertise. The rest of the document focuses on big data integration, with sections on the challenges of integrating big data, choosing Hadoop as a solution, and different approaches to integration including using open source frameworks, suites, and custom connectors. Throughout there are examples of use cases and how companies are leveraging big data and integration to solve business problems. The overall message is that in order to get full value from data, you need to integrate different sources, and that big data integration approaches have advanced to make this more achievable.

Technology perspective How to process big data? © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
How to process big data? The critical flaw in parallel ETL tools is the fact that the data is almost never local to the processing nodes. This means that every time a large job is run, the data has to first be read from the source, split N ways and then delivered to the individual nodes. Worse, if the partition key of the source doesn’t match the partition key of the target, data has to be constantly exchanged among the nodes. In essence, parallel ETL treats the network as if it were a physical I/O subsystem. The network, which is always the slowest part of the process, becomes the weakest link in the performance chain. http://blog.syncsort.com/2012/08/parallel-etl-tools-are-dead © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

How to process big data? “A big part of [the company’s strategy] includes wiring SQL Server 2012 (formerly known by the codename “Denali”) to the Hadoop distributed computing platform, and bringing Hadoop to Windows Server and Azure” Even Microsoft (the .NET house) relies on Hadoop since 2011 © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
What is Hadoop? Apache Hadoop, an open-source software library, is a framework that allows for the distributed processing of large data sets across clusters of commodity hardware using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
Map (Shuffle) Reduce Simple example • Input: (very large) text files with lists of strings, such as: „318, 0043012650999991949032412004...0500001N9+01111+99999999999...“ • We are interested just in some content: year and temperate (marked in red) • The Map Reduce function has to compute the maximum temperature for every year Example from the book “Hadoop: The Definitive Guide, 3rd Edition” © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

camel-pig? camel-hive? camel-hcatalog? Not available yet (current Camel version: 2.12)  Workarounds: • • • Use Pig / Hive-Query scripts (via camel-exec connector or any scripting language) Build your own connector (more details later ...) Use Hive-Hbase-Integration and store data in HBase ( „ugly“) © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
camel-avro connector Camel is not just about connectors ... Camel supports a pluggable DataFormat to allow messages to be marshalled to and unmarshalled from binary or text formats, e.g. CSV, JSON, SOAP, EDI, ZIP, or ... ... Avro, a data serialization system used in Apache Hadoop. camel-avro connector provides a dataformat for Avro, which allows serialization and deserialization of messages using Apache Avro's binary data format. Moreover, it provides support for Apache Avro's RPC, by providing producers and consumers endpoint for using Avro over Netty or HTTP. © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

Potential Uses of Clickstream Data One of the original uses of Hadoop at Yahoo was to store and process their massive volume of clickstream data. Now enterprises of all types can use Hadoop to refine and analyze clickstream data. They can then answer business questions such as: • • • What is the most efficient path for a site visitor to research a product, and then buy it? What products do visitors tend to buy together, and what are they most likely to buy in the future? Where should I spend resources on fixing or enhancing the user experience on my website? Goal: Data visualization can help you optimize your website and convert more visits into sales and revenue.

  • 22. Technology perspective How to process big data? © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
  • 23. How to process big data? The critical flaw in parallel ETL tools is the fact that the data is almost never local to the processing nodes. This means that every time a large job is run, the data has to first be read from the source, split N ways and then delivered to the individual nodes. Worse, if the partition key of the source doesn’t match the partition key of the target, data has to be constantly exchanged among the nodes. In essence, parallel ETL treats the network as if it were a physical I/O subsystem. The network, which is always the slowest part of the process, becomes the weakest link in the performance chain. http://blog.syncsort.com/2012/08/parallel-etl-tools-are-dead © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

  • 26. How to process big data? “A big part of [the company’s strategy] includes wiring SQL Server 2012 (formerly known by the codename “Denali”) to the Hadoop distributed computing platform, and bringing Hadoop to Windows Server and Azure” Even Microsoft (the .NET house) relies on Hadoop since 2011 © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
  • 27. What is Hadoop? Apache Hadoop, an open-source software library, is a framework that allows for the distributed processing of large data sets across clusters of commodity hardware using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner
  • 28. Map (Shuffle) Reduce Simple example • Input: (very large) text files with lists of strings, such as: „318, 0043012650999991949032412004...0500001N9+01111+99999999999...“ • We are interested just in some content: year and temperate (marked in red) • The Map Reduce function has to compute the maximum temperature for every year Example from the book “Hadoop: The Definitive Guide, 3rd Edition” © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

Camel supports a pluggable DataFormat to allow messages to be marshalled to and unmarshalled from binary or text formats, e.g. CSV, JSON, SOAP, EDI, ZIP, or ... ... Avro, a data serialization system used in Apache Hadoop. camel-avro connector provides a dataformat for Avro, which allows serialization and deserialization of messages using Apache Avro's binary data format. Moreover, it provides support for Apache Avro's RPC, by providing producers and consumers endpoint for using Avro over Netty or HTTP. © Talend 2013 “Big Data beyond Hadoop – How to integrate ALL your Data” by Kai Wähner

  • 61. Potential Uses of Clickstream Data One of the original uses of Hadoop at Yahoo was to store and process their massive volume of clickstream data. Now enterprises of all types can use Hadoop to refine and analyze clickstream data. They can then answer business questions such as: • • • What is the most efficient path for a site visitor to research a product, and then buy it? What products do visitors tend to buy together, and what are they most likely to buy in the future? Where should I spend resources on fixing or enhancing the user experience on my website? Goal: Data visualization can help you optimize your website and convert more visits into sales and revenue.
