The document discusses how Talend can be used for big data integration and analysis. It explains that Talend provides a graphical interface for creating ETL jobs that can execute on Hadoop, allowing users to work with big data technologies like HDFS, Hive, and Pig without writing code. The document also presents a banking use case where Talend and big data were used to structure and analyze unstructured log data to gain business insights. A demo is shown of how Talend can be used to extract, transform, and load data and perform analysis on Hadoop in an integrated way.

- 4. www.edureka.co/talend-for-big-data ETL with Big Data A Graphical Abstraction Layer on top of Hadoop Applications – this makes life so much easy in the Big Data buzz world » What no one seems to question in response to these sorts of comments is the naive assumptions these statements are based on !! » Is it realistic for most companies to move all of their data into Hadoop? The typical assertion is that "Hadoop eliminates the need for ETL”…. Seriously ?

- 6. www.edureka.co/talend-for-big-data ETL with Big Data Is writing ETL scripts in MapReduce code still ETL? Is ETL running faster (in few cases & slower in others) on Hadoop eliminating ETL? Is introduction of Hadoop changing when, where and how ETL happens? The question isn't really that are we eliminating ETL, but where does ETL take place & how are we changing its definition Yes No Yes
- 8. www.edureka.co/talend-for-big-data Defining ETL E • Represents the ability to consistently and reliably extract data with high performance and minimal impact to the source system T • Represents the ability to transform one or more data sets in batch or real-time into a consumable format L • Stands for loading data into a persistent or virtual data store

- 12. www.edureka.co/talend-for-big-data Why Talend? Talend is the only Graphical User Interface tool which is capable enough to “translate” an ETL job to a MapReduce job. Thus, Talend ETL job gets executed as a MapReduce job on Hadoop and get the big data work done in minutes This is a key innovation which helps to reduce entry barriers in Big Data technology and allows ETL job developers (beginners and advanced) to carry out Data Warehouse offloading to greater extent With its Eclipse-based graphical workspace, Talend Open Studio for Big Data enables the developer and data scientist to leverage Hadoop loading and processing technologies like HDFS, HBase, Hive, and Pig without having to write Hadoop application code Hadoop Applications, Seamlessly gets Integrated within minutes using Talend
- 13. www.edureka.co/talend-for-big-data Why Talend? By simply selecting graphical components from a palette, arranging and configuring them, you can create Hadoop jobs For example: 1. Load data into HDFS (Hadoop Distributed File System) 2. Use Hadoop Pig to transform data in HDFS 3. Load data into a Hadoop Hive based data warehouse 4. Perform ELT (extract, load, transform) aggregations in Hive 5. Leverage Sqoop to integrate relational databases and Hadoop
- 15. www.edureka.co/talend-for-big-data Talend Hadoop Integration For Hadoop applications to be truly accessible to your organization, they need to be smoothly integrated into your overall data flows Talend Open Studio for Big Data is the ideal tool for integrating Hadoop applications into your broader data architecture Talend provides more built-in connector components than any other data integration solution available, with more than 800+ connectors that make it easy to read from or write to any major file format, database, or packaged enterprise application For Example, in Talend Open Studio for Big Data, you can use drag 'n drop configurable components to create data integration flows that move data from delimited log files into Hadoop Hive, perform operations in Hive, and extract data from Hive into a MySQL database (or Oracle, Sybase, SQL Server, and so on)
- 16. www.edureka.co/talend-for-big-data Talend Hadoop Integration More and more enterprise wanted to scale up in Hadoop/Big Data technologies with use of existing pool of talent and reduce overspending on map-reduce programmer (which is pretty new and expensive) High rise of job trend in Data Scientist/Data Analysis (Talend also comes along with basic BI transformations which reduces your dependency on simple excel dash board/ BI tools) Gartner is featuring Talend as the best technology in market for Data Integration and Big Data 3 major players in Big Data industry, Hortonworks, Cloudera, MapR have already tied up with Talend for big data solutions And mostly any level person in industry can quickly get started on this without much pre-requisites Myth : I don’t know Java programming , how would this course help me learn and excel in Big Data? The biggest advantage you get with Talend for Big Data is “there is no prerequisite” to learn this concept. Whether you come with prior knowledge of Hadoop or not , this course has some or other best things to offer

- 21. www.edureka.co/talend-for-big-data Real time Use Case:Talend(data analysis)+ BigData A Banking industry use case : “Addressing the challenges in growing the business with use of flexible data analysis hybrid Big Data tool“ . We used a completely unstructured log data , which need to be structured then analysed and then business sense has to come from it and imagine if all of that has to happen on top of haddop ? Lets see the magic. In this section, you will be able to sense the true power of Talend+Big Data
- 22. www.edureka.co/talend-for-big-data Project Use Case It is not only a question of standard ETL tool and how best it can offer integration features. The question is what else it has to offer for current pain areas in enterprise level so that without extra efforts like 1. resource investment 2,skills 3.training 4.license investment , we still can manage all of that in one tool. Yes that’s possible to some extent. How ?
