Vertica and Hadoop for Big Data

Here is what I’ve jotted down during Vertica’s webinar Hadoop vs. RDBMS for Big Data Analytics: Why Choose?

  • the webinar has focused on clarifying where and how Vertica and Hadoop fit in the Big Data space
  • Vertica’s strenghts:
    • support for SQL, extended SQL, and analytics making it interactive investigation of data
    • storage space efficiency — I don’t think it’s correct to interpret Hadoop data redundancy as storage space inneficiency
    • analytics SDK (allows customizing in-database analytic functions)
    • ease of operating and maintenance (auto-tunning features)
  • the following slide is pretty eloquent about Hadoop and Vertica being complementary solutions : Vertica vs Hadoop - Analytics Feature Comparison
  • when covering a scenario for using both Hadoop and Vertica, they chose the ease one: Hadoop as ETL. It’s not that it’s not a good one, but it’s the only one databases vendors are using these days when speaking about integration with Hadoop.

    Hadoop + Vertica Use Case Example

  • other possible Hadoop + Vertica use cases:

    • Filter, join, and aggregation in Vertica with intermediate results fed into MR jobs
    • parallel import and export to HDFS
    • Hadoop MapReduce for data transformation and Vertica for optimized storage and retrieval
  • there will be a community edition of Vertica. It was announced in October for the end of 2011, but I don’t think it’s out yet
  • there’s a GitHub repo for user defined extensions for Vertica
  • the following categorization of Big Data tools is interesting but feels in favor of Vertica which would be placed somewhere close to the center of the triangle
