  1. First Look at "Project Velocity"

    Siddharth Jagtiani Sr. Program Manager | MS India Development Center Janakiram MSV Sr. Technology Strategist | MS India Development Center
  2. Agena The need for memory cache Key scenarios for using memory cache Introducing “Project Velocity” “Project Velocity” features How do I use “Project Velocity”?
  3. The Need For Memory Cache
  4. Key Scenaros for Memory Cache Reference Data Frequently accessed data Read-only Activity Data Data is generated from an activity Read-Write Will “retire” at the end of activity Resource Data Close to the data tier Concurrent Read-Write operations
  5. Caching Reference Data Scenario: Social Networking Clients Web Tier Distributed Cache Servers Local Cache (in Proc) Usernames, Name-> ID Mapping Data Tier Friend Lists Usernames
  6. Caching Activity-Oriented Data Clients Scenario: Enterprise LOB Application Web Tier Application Tier Integration Hub Distributed Cache Aggregated Vendor Catalogs Order, Invoice, Payment Data Tier Vendor services Pricing Vendor Sources
  7. Caching Resource-Oriented Data Scenario: Flight Inventory and Pricing Booking Service Application Tier Flight Itinerary Seat Inventory Distributed Cache Flight Segment Flight Price Airlines
  8. What is "Project Velocity"? An explicit, distributed, in-memory application cache for all kinds of data (CLR objects, rows, XML, Binary data etc.) Fuse "memory" across machines into a unified cache Clients can be spread across machines or processes Clients Access the Cache as if it was a large single cache Unified Cache View Cache Layer distributes data across the various cache nodes

  11. "Velocity" Concepts Velocity Service Velocity Service Velocity Service Velocity Service Named Cache : Product Catalog Named Cache : Electronics Inventory Regions Key Payload Tags Region A 121 xxxx “Toy” “Child” 123 yyyy “Toy” “Chair”.. Machine -> Cache Host -> Named Caches -> Regions -> Cache Items -> Objects Host Physical processes hosting Velocity instance. Named Caches Can span across machines Defined in the configuration file Regions Physically co-located Container of Cache Items May be implicit or explicitly created Cache Item Key, Payload (Object ), Tags, TTL, Timestamps, Version
  12. Example Usage Of Velocity API // Create instance of cachefactory (reads appconfig) CacheFactoryfac = new CacheFactory(); // Get a named cache from the factory Cache catalog = fac.GetCache("catalogcache"); // Simple Get/Put catalog.Put("toy-101", new Toy("Puzzle", .,.)); // From the same or a different client Toy toyObj = (Toy)catalog.Get("toy-101"); // Region based Get/Put catalog.CreateRegion("toyRegion"); // Both toy and toyparts are put in the same region catalog.Put("toyRegion", "toy-101", new Toy( .,.)); Catalog.Put("toyRegion", "toypart-100", new ToyParts(…)); Toy toyObj = (Toy)catalog.Get("toyRegion", "toy-101");
