- 4. There’s data, and then there’s Big data. So, what’s the difference? Presenter: Waqas Idrees
- 5. What is Big Data? • Big Data = All Data • Big data is the collection and analysis of information from various sources.
- 6. What is Big Data? • Big Data sets can include o Structured o Semi Structured o Unstructured
- 7. What is Big Data? 3Vs Big data is characterized by the three Vs 1. An extreme volume of data. 2. A broad variety of types of data. 3. The velocity at which the data need needs to processed and analyzed.
- 8. Who Uses Big Data? Companies considering big data as an integral part of their strategy because • It gives businesses the power to pinpoint the cause of their problems. • Customers’ buying habits.
- 9. Who Uses Big Data? • They can optimize offerings • They can reduce cost and time It helps them to make sound decisions
- 10. Azure Data Lake Presenter: Waqas Idrees

- 26. U-SQL Language Overview U-SQL Fundamentals • All the familiar SQL Clauses SELECT | FROM | WHERE | GROUP BY | OVER • Operate on Structure and Unstructured Data .NET Integration and Extensibility • U-SQL Expressions are full C# expressions • Reuse .NET code in other assemblies • Use C# to define your own Types | Functions | Aggregations | IO
- 27. ADLA Executions U-SQL Cloud Execution • The data read or written by the script will also be in Azure - typically in an Azure Data Lake Store account • You pay for any compute and storage used by the script.
- 28. ADLA Executions U-SQL Local Execution • The data read and written by this script will be on you own machine. • There is no additional cost

- 30. First U-SQL Script • Create new Azure Data Lake > U-SQL Project. • An empty U-SQL script and its code behind file will be there called "Script.usql"
- 31. First U-SQL Script @searchlog = EXTRACT UserId int, Start DateTime, Region string, Query string, Duration int?, Urls string, ClickedUrls string FROM "/Samples/Data/SearchLog.tsv" USING Extractors.Tsv(); OUTPUT @searchlog TO "/output/SearchLog-first-u-sql.csv" USING Outputters.Csv(); Row set Apply schema on read File Path Write out Easy delimited text handling
- 32. ADLA Local Account Configurations Location of inputs and Outputs
- 35. Job Life Cycle
- 36. When does a job get Queued? Local Cause • Queue is already at max concurrency Cloud Clause • Shortage of Azure Data Lake Analytics Units (ADLAUs) • Queue is already at max concurrency
- 37. Azure Data Lake Account Configurations Presenter: Waqas Idrees
- 38. ADLA Cloud Account Configurations • Maximum number of ADLA accounts per subscription per region: 5 • Maximum number of concurrent U-SQL jobs per account: 20 • Maximum number of Analytics Units (AUs) per account: 32 • Maximum number of Analytics Units (AUs) per job: 32
- 39. What is an Azure Data Lake Analytics Unit? An Azure Data Lake Analytics Unit (AU) is a unit of compute resources with Azure Data Lake. AU is the equivalent of 2 CPU cores and 6 GB of RAM
- 40. How AUs are used during U-SQL Query Execution? When we submit a U-SQL job, e specify three things 1. U-SQL Script 2. Input and Output Files 3. Reserved AUs
- 41. How AUs are used during U-SQL Query Execution? U-SQL Compiler and Optimizer Vertex/Vertices Each Task in a Plan is called Vertex. Plan
- 42. How AUs are used during U-SQL Query Execution? • We need an AU to run a Vertex. • When the vertex is finished the AU will be assigned to another vertex.
- 43. How AUs are used during U-SQL Query Execution?
- 45. What is an AU Second? An AU Second is the unit used to measure the compute resources used for a job.
- 46. What is an AU Second? • 1 AU for a job that executes for 1 second = 1 AU Second. • 1 AU for a job that executes for 1 minute (60 seconds) = 60 AU Seconds. • 2 AUs for a job that executes for 100 seconds = 200 AU Seconds. • 10s AUs for a job that executes for 5 minutes (300 seconds) = 3000 AU Seconds.

Editor's Notes
- #4: - Multiple definitions of Big Data are available on internet. - In general Big Data refers to set of data that are so large in volume and so complex that current data processing products are not capable of managing, capturing or processing of that data within a reasonable amount of time.
- #6: - Big Data is all data which can be mined for insights. - Big Data is collection and analysis of data from various sources such as websites, social media, mobile apps, sensors internet of things or data collected from the scientific experiment.
- #9: Companies find big data as an integral part of their strategy because it can reduce cost and time, develop new products, optimize offerings, and help you make sound decisions.
- #10: It gives businesses the power to pinpoint the cause of their problems and other behaviors such as customers’ buying habits and risk portfolios. I'll represent more advance topics on this.
- #13: 1- Azure Data Lake was built on the learning and technologies of cosmos. 2- Cosmos is Microsoft's internal BigData analysis platform. 2.1 There's not a lot of public information available about cosmons. 3- Cosmos is used within Microsoft extensively, across a huge number of servers.
- #14: 4- It is used to store and process data for applications such as Azure, AdCenter, Bing, MSN, Skype and Windows Live. 5- They are collecting information on our every click, visual search for improving their services, adds expreiences after performing analysis on that data.
- #15: Yarn allows different data processing engines like graph processing, interactive processing, stream processing as well as batch processing to run and process data stored in HDFS
- #51: Hadoop comes in many different flavors, some running on-premises, others running in the cloud. Some are managed BY you, others are managed FOR you Most Big Data cloud offerings that are available are priced per hour based on how long you keep your cluster up and running. ADLA takes a different approach to pricing.
