PSSUG Nov 2012: Big Data with SQL Server

  1. 1. Big Data with SQL ServerPhilly SQL Server User GroupNovember 2012Mark KromerRazorfish BI & Big Data Technology Director
  2. 2. What we’ll (try) to cover tonight‣ What is Big Data?‣ The Big Data and Apache Hadoop environment‣ Big Data Analytics‣ SQL Server in the Big Data world‣ How we utilize Big Data @ Razorfish 2
  3. 3. Big Data 101‣ 3 V’s ‣ Volume – Terabyte records, transactions, tables, files ‣ Velocity – Batch, near-time, real-time (analytics), streams. ‣ Variety – Structures, unstructured, semi-structured, and all the above in a mix‣ Text Processing ‣ Techniques for processing and analyzing unstructured (and structured) LARGE files‣ Analytics & Insights‣ Distributed File System & Programming
  4. 4. Mark’s Big Data Myths‣ Big Data ≠ NoSQL ‣ NoSQL has similar Internet-scale Web origins of Hadoop stack (Yahoo!, Google, Facebook, et al) but not the same thing ‣ Facebook, for example, uses Hbase from the Hadoop stack‣ Big Data ≠ Real Time ‣ Big Data is primarily about batch processing huge files in a distributed manner and analyzing data that was otherwise too complex to provide value ‣ Use in-memory analytics for real time insights‣ Big Data ≠ Data Warehouse ‣ I still refer to large multi-TB DWs as “VLDB” ‣ Big Data is about crunching stats in text files for discovery of new patterns and insights ‣ Use the DW to aggregate and store the summaries of those calculations for reporting
  5. 5. ‣ Batch Processing‣ Commodity Hardware‣ Data Locality, no shared storage‣ Scales linearly‣ Great for large text file processing, not so great on small files‣ Distributed programming paradigm
  6. 6. Big Data Analytics Web Platform
  7. 7. In-Database Analytics (Teradata Aster)• Because of built-in analytics functions and big data performance, Aster becomes the data scientist’s sandbox and BI’s big data analytics processor. Prepackaged Analytics Functions (including Attribution)
  8. 8. SQL Server Big Data – Data LoadingAmazon HDFS & EMR Data Loading Amazon S3 Bucket
  9. 9. SQL Server Big Data Environment‣ SQL Server Database ‣ SQL Server 2008 R2 or 2012 Enterprise Edition ‣ Page Compression ‣ 2012 Columnar Compression on Fact Tables ‣ Clustered Index on all tables ‣ Auto-update Stats Asynch ‣ Partition Fact Tables by month and archive data with sliding window technique ‣ Drop all indexes before nightly ETL load jobs ‣ Rebuild all indexes when ETL completes‣ SQL Server Analysis Services ‣ SSAS 2008 R2 or 2012 Enterprise Edition ‣ 2008 R2 OLAP cubes partition-aligned with DW ‣ 2012 cubes in-memory tabular cubes ‣ All access through MSMDPUMP or SharePoint
  10. 10. Wrap-up‣ What is a Big Data approach to Analytics? ‣ Massive scale ‣ Data discovery & research ‣ Self-service ‣ Reporting & BI‣ Why did we take this Big Data Analytics approach? ‣ Each Web client produces an average of 6 TBs of ICA data in a year ‣ The data in the sources are variable and unstructured ‣ SSIS ETL alone couldn’t keep up or handle complexity ‣ SQL Server 2012 columnstore and tabular SSAS 2012 were key to using SQL Server for Big Data ‣ With the configs mentioned previously, SQL Server is working great‣ Analytics on Big Data also requires Big Data Analytics tools ‣ Aster, Tableau, PowerPivot, SAS
