Big Data's Big Picture, Real-Time Queries, Real-Time Queries, Single-Process Real-Time Queries

  1. Big Data: the Big Picture (Vimeo) — Jim Stogdill’s excellent talk: although Big Data is presented as part of the Gartner Hype Cycle, it’s an epoch of the Information Age which will have significant effects on the structure of corporations and the economy.
  2. Impala (github) — Cloudera’s open source (Apache) implementation of Google’s F1 (PDF), for realtime queries across clusters. Impala is different from Hive and Pig because it uses its own daemons that are spread across the cluster for queries. Furthermore, Impala does not leverage MapReduce, allowing Impala to return result in real-time. (via Wired)
  3. druid (github) — open source (GPLv2) a distributed, column-oriented analytical datastore. It was originally created to resolve query latency issues seen with trying to use Hadoop to power an interactive service. See also the announcement of its open-sourcing.
  4. Supersonic (Google Code) — an ultra-fast, column oriented query engine library written in C++. It provides a set of data transformation primitives which make heavy use of cache-aware algorithms, SIMD instructions and vectorised execution, allowing it to exploit the capabilities and resources of modern, hyper pipelined CPUs. It is designed to work in a single process. Apache-licensed.
