Colossus metadata is stored in Bigtable: see https://cloud.google.com/blog/products/storage-data-transfer... Spanner stores its data in Colossus, so there would be some bootstrappi…

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)

For those interested in a technical overview, http://kudu.apache.org/kudu.pdf is our academic-style (but not submitted to any journal) paper.

Apache Kudu project founder here: It's true that the project was initially developed at Cloudera, and employees continue to be the main driving force behind development. That said,…

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 in…

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

Todd from the Kudu team here if anyone has any questions, I'll check back throughout the day (or tweet at @ApacheKudu)

FYI on the date issue, lest anyone think we filed the patent trying to steal the work done by others, the patent application says: "This application claims to the benefit of U.S. P…

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 wou…

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: http…

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 c…

Also worth noting it's an open source project so if you're interested in contributing in this area, we'd love to have you on board.

We've just updated to C++11 as of a couple weeks ago. Partially the issue was when it started, partially the issue is that we have to support older platforms and we have a C++ clie…
