  • Building a Startupwith NoSQL

    Sebastian Cohnen, @tisbastormforger.com, @StormForgerApp

    NoSQL Matters Barcelona 2014

  • About me Sebastian Cohnen, M. Sc.

    Developer & Founder from Cologne, Germany

    (Web-) Architectures, Performance & Scalability

    Founder of StormForger.com(services around load testing HTTP-based systems)

  • Startups agile & open minded

    small teams, pragmatic

    solve new problems

  • NoSQL?

    "A NoSQL (often interpreted as Not Only SQL) database provides a mechanism for storage and

    retrieval of data that is modeled in means other than the tabular relations used in relational databases."


    "Motivations for this approach include simplicity of design, horizontal scaling and finer control over


  • NoSQL

    Ease of use (development & operations)

    Very special problem

  • StormForger

  • StormForger load and performance testing of HTTP APIs

    SaaS product

    plan, configure and execute tests

    analyze and compare results

  • We are a startup!

  • Our Needs handle highly structured, complex data

    ingest, process and query time series data

    caching of structured data

    centralized logging and log analysis

  • How to find the perfect solution?

  • There isn't one :-/

  • Polyglot Persistence


  • but be careful What are the downsides and tradeoffs?

    Availability of tooling?

    How mature is the technology?

    What about (community or commercial) support?

  • Back to StormForger's needs

  • SQL-ish, declarative query language

    easy to get started with

    powerful background/stream processing

    Time Series Data

  • Caching

    very, very fast

    primitive functions to work with data structures

    awesome community

  • ELK (Elastic Search + Logstash + Kibana)

    Centralized, aggregated logging

    Great analysis and search features


  • Structured Data

    Not really tackled yet

    For now: serialize and store as TEXT in RDMS

  • Structured Data (2)

    we already evaluated some solutions

    great query language (AQL)

    support for JOINS & Graphs

  • Conclusion focus on ease of use aspects

    be pragmatic and think agile

    pick the right tool for the job

  • And if you think you found the right solution

    there are always alternatives

  • What about using a SQL DB for NoSQL?

  • PostgreSQL hstore: Key/Value

    json & jsonb: JSON data

    just use your existing tools

    query via SQL, indexable,

  • Thanks!
