  7. Flip Flops Core 1993 ~$25/mb; $26,214,400/tb 2014 ~$0.007/mb; $7,645/tb ICs on board SIMMs DIMMS Big Drives Floppy Small Drives Flash SSD

  8. Oracle Database In-Memory Goals Exploit latest generation hardware Accelerate OLTP No Changes to Applications Real Time Analytics CPU

  9. Row Format Databases vs. Column Format Databases Row SALES • Transactions run faster on row format • Example: Insert or query a sales order • Fast processing few rows, many columns Column • Analytics run faster on column format • Example : Report on sales totals by region • Fast accessing few columns, many rows SALES Until Now Must Choose One Format and Suffer Tradeoffs

  10. Oracle In-Memory Columnar Technology Pure in-memory column format Not persistent, and no logging Quick to change data: fast OLTP 2x to 20x compression Enabled at table or partition level Available on all hardware platforms Pure In-Memory Columnar SALES

  11. Scans Billions of Rows per Second per CPU Core Memory Each CPU core scans local in-memory columns Scans use fast SIMD vector instructions Originally designed for graphics & science Billions of rows/sec scan rate per CPU core Example: Find all sales in region of CA REGION CPU CA Load multiple region values Vector Compare all values an 1 cycle CA CA Vector Register CA > 100x Faster

  14. Querying JSON Sample JSON in column customers.document select c.document.firstName, c.document.lastName, c.document.address.city, c.document.phoneNumbers from customers c; Simplified syntax for simple queries { "firstName": "John", “lastName”: "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021“, "isBusiness" : false}, "phoneNumbers": [ { "type": "home", "number": "212 555-1234“ }, { "type": "fax", "number": "646 555-4567“ } ] }

  15. Oracle REST Data Services Enabling RESTful access to Oracle Database • Provides data access consistent with modern App Dev frameworks • Can map standard http(s) URI RESTful gets and posts to SQL • Can declaratively returns results in JSON format • JavaScript framework friendly • Can support high numbers of end users • Services • HTTP(s) relational data access • Oracle JSON collection based schemaless access • Oracle NoSQL access over HTTP • Oracle APEX mid-tier, web toolkit applications, mod_plsql replacement • Formally known as Oracle APEX Listener • Supported feature of the Oracle Database since 2010 • Ships with Oracle Database 12cRelease 1 (12.1.0.2)

  16. Oracle REST Data Services Schemaless development using JSON Collection API (12.1.0.2) Oracle REST Data Services Auto Generated SQL JSON Collection API URI Pass Back JSON Transform JSON Oracle Database HTTP(S) client • Data stored in Oracle Database as JSON documents • App Developer make standard HTTP(S) calls to JSON Collection APIs

  17. Oracle REST Data Services Serving JSON results from relational data Oracle REST Data Services URI Map and Bind SQL Transform to JSON JSON Transform SQL Result Set HTTP(S) client Oracle Database • Data stored in standard relational tables and columns • Oracle REST Data Services (ORDS) Developer defines URI<>SQL mapping • App Developer calls named URI over HTTP(S) gets and posts

  20. SQL is Critical “….the complexity of dealing with a non-ACID data store in every part of our business logic would be too great, and there was simply no way our business could function without SQL queries.” Google, VLDB 2013 “[Facebook] started in the Hadoop world. We are now bringing in relational to enhance that. ... [we] realized that using the wrong technology for certain kinds of problems can be difficult.” Ken Rudin, Facebook, TDWI 2013 http://tdwi.org/articles/2013/05/06/facebooks-relational-platform.aspx https://www.linkedin.com/groups/Find-out-why-Google-decided-4434815.S.273792742

  33. Performance Improvements

  34. Advanced Index Compression Compresses indexes to reduce their overall storage requirement Less space required on disk Better use of the database cache Indexes are compressed by between 1 – 3 times Little or no discernable overhead Compression Advisor extended to describe the possible benefits of this feature

  35. Attribute Clustering Ordering of data so that rows are stored near one another based on column values Improved query performance and concurrency Reduced physical data access trough smart IO Significant IO reduction for highly selective operations Optimized space utilization Less need for indexes Improved compression ratios through data clustering Full application transparency Any application will benefit Benefits :

  36. Zone Maps Persisted storage index Stores minimum and maximum of specified columns Analogous to a coarse index structure Much more compact than an index Zone maps filter out what you don’t need, indexes find what you do need Significant performance benefits with complete application transparency IO reduction for table scans with predicates on the table itself or even a joined table using join zone maps (a.k.a. “hierarchical zone map”) Benefits are most significant with ordered data Used in combination with attribute clustering or data that is naturally ordered

  37. Approximate Count Distinct Not every query requires a completely accurate result “How many distinct individuals visited our website last week?” New SQL function for approximate results for COUNT DISTINCT aggregates APPROX_COUNT_DISTINCT() Approximate results can be significantly faster and use less resources than exact calculations 5x to 50x ++ times faster (depending upon number of distinct values and complexity of SQL) Accuracy > 97% (with 95% confidence)

  38. Rapid Home Provisioning

  39. Oracle Rapid Home Provisioning Install Once Use Many Patching is complex and time consuming Even when automated New way to deploy upgrades Create reference homes on Centralized Home Server Apply patches once (Enterprise) on Home Server Distribute homes on-demand or policy Fast and Efficient Rapid distribution (network efficient) Space efficient (snapshots) Local caches
