  • Nice review. The 2012 update: GT.M is currently being deployed as a national banking database for 60 million customers. Yes - one database, that touches and updates each of these accounts every day, in real time. Impressive!

    GT.M: A Tried and Tested Open-Source NoSQL Database GT.M: A Tried and Tested Open-Source NoSQL Database Presentation Transcript

    • GT.M: A Tried and Tested Open-Source NoSQL Database Rob Tweed: M/Gateway Developments Ltd & KS Bhaskar: FIS
    • NoSQL / Schema-less DBs
      • Many contenders, eg:
        • CouchDB
        • MongoDB
        • Voldemort
        • Cassandra
        • Dynomite
        • HBase
        • HyperTable
        • VPork
        • Tokyo Cabinet
      • Schema-less, “key-value”, often hierarchical
      • Free Open Source
      • Design Goal: massive scalability + very high performance
      • But all are new!
    • New versus Tried and Tested
      • Any existing alternatives? ie featuring:
        • Schema-less, key-pair architecture
        • Massive scalability
        • Extremely high performance
        • Ability to start small, grow to any size

    • GT.M: Key-pair database
      • Schema-free, key-pair database
      • Schema implicit in application
      • Persistent multi-dimensional sparse arrays
      • ^Offices( "UK")=2
      • ^Offices ( "UK","London")="+44 20 8123 1999"

    • GT.M – Where do you get it?
      • Home page:
        • http://fis-gtm.com
      • Stand-alone:
        • http://sf.net/projects/fis-gtm
      • Bundled with VistA:
        • http://sf.net/projects/worldvista
      • Bundled with M/DB installer:
        • http://bit.ly/4xzkRQ
    • GT.M: ideal for use in the Cloud
      • M/DB
        • Free Open Source alternative to SimpleDB
        • API-compatible
          • Behaves identically
          • Accessed identically
          • Just a different endpoint URL
        • Designed for:
          • Local use
          • Private Cloud
          • Alternative Public Cloud to Amazon
    • M/DB v Amazon SimpleDB
      • Limitations that M/DB addresses:
        • Number of “domains”
        • Data types and record sizes
          • Text only
          • 1k maximum
        • Can be costly
        • Eventual Consistency
        • Locked in to Amazon’s Cloud
      • M/DB: the SimpleDB model can be used anywhere
    • SimpleDB Client m_apache gateway + xinetd GT.M M/DB Security M/DB Methods Ubuntu (or other) Linux Physical or Virtual Machine HTTP Request XML Response creation HTTP Response M/DB Database m_python gateway Python M/DB APIs M/DB Appliance Architecture Web Server (Apache)
    • M/DB
      • In Ubuntu 9.10 Enterprise Cloud (UEC):
        • M/DB to be available in the UEC Image Store
        • Fills the missing gap in UEC: SimpleDB API
    • M/DB
      • Why GT.M was the ideal technology:
        • Rapid development
          • M/DB version 1.0: 1 week!
        • At high-end:
          • Massive scalability and ultra-high performance
        • At low-end:
          • Undemanding of hardware and Free Open Source
