SQL on Hadoop: An overview of frameworks and their applicability

An overview of the 3 SQL-on-Hadoop execution models — batch (10s of minutes and up), interactive (up to minutes), operational (sub-second), their applicability in the field of applications, and the main characteristics of the tools/frameworks in each of these categories:

Within the big data landscape there are multiple approaches to accessing, analyzing, and manipulating data in Hadoop. Each depends on key considerations such as latency, ANSI SQL completeness (and the ability to tolerate machine-generated SQL), developer and analyst skillsets, and architecture tradeoffs.

The usual suspects are included: Hive, Impala, Preso, Spark/Shark, Drill.

A prolific season for Hadoop and its ecosystem

In 4 years of writing this blog I haven’t seen such a prolific month:

  • Apache Hadoop 2.2.0 (more links here)
  • Apache HBase 0.96 (here and here)
  • Apache Hive 0.12 (more links here)
  • Apache Ambari 1.4.1
  • Apache Pig 0.12
  • Apache Oozie 4.0.0
  • Plus Presto.

Actually I don’t think I’ve ever seen such an ecosystem like the one created around Hadoop.
