Just a small note: Kudu shares no code or provenance with Hadoop. Only commonality is ecosystem (eg you can use spark or Impala to query it)

Hopefully this isn't too "pitch"-y, but: if you're looking for a database that's good at time series, will always be open source, and does support scale-out and HA, you might be interested in Apache Kudu (incubating

Suggestion: add an option to look at file contents and analyze cross-file dependencies (eg c/c++ #includes or java imports)

Agreed -- personally I'm against offensive use of patents like this as well, and it's my understanding that Cloudera doesn't intend to use this patent offensively. If it did, I would be upset and would consider leaving the co

Kudu uses a similar algorithm which we call HybridTime. You can read the tech report here: http://pdsl.ece.utexas.edu/david/hybrid-time-tech-report-01.... and the source here: https://github.com/apache&

Typically QSBR algorithms don't require blocking the world, or even blocking any single thread. They just require each thread to periodically check in and run a bounded amount of code which amounts to "hey, I'm not currently
