Cassandra 2.0 can handle 5TB per node easily, 10TB with some care. Best to scale out, not up. That said, if someone else has already made the hardware choice for you, you can always run multiple C* nodes on a single machine. I know severa

It sounds like you're assuming that productivity and power are opposites. Four years ago or even two, Cassandra was much harder to develop against than MongoDB, but that's not the case today.

Like other resource misallocations, this would be a non-issue if water were priced at market rates.

The crucial distinction is that buying shares is not a zero sum game; it's possible for all investors to "win." This is not the case in gambling or commodities markets; for me to win, someone else has to lose.

Interesting. FWIW, this isn't 30 hz vs 60 hz. My windows box is limited to the same 30 hz and has no issues.

On the ~2011 model I'm using in the office, right brace is exactly under the question mark and semicolon. It's not staggered to the right at all.

Bracket/brace are fine if you use your little finger properly. Really it's a better position than "standard" keyboards since you only have to reach down vertically instead of having to move laterally as well which reduc

So basically, VoltDB acknowledges that cross-partition transactions are Hard and has put a lot of effort into minimizing them. (This is basically the entire point of the original HStore paper.) InfiniSQL says don't worry, we'll j

Commits-since-fork might be a better measure than stars, e.g. most of the starred forks of brianfrankcooper/YCSB have no commits more recent than the mainline.

SSDs really are 1000x faster at random writes (~200,000 iops vs ~200 iops)

No. Most database engines are actually so old they were developed even before HDD hit the seek wall.

Not three orders of magnitude faster, which is the difference between hdd and ssd random writes.

Cassandra offers a mix of commutative operations (sets, maps, increments), an eventlog model, and lightweight (paxos-based) transactions. Unlike a key/value database like Riak, Cassandra can update individual fields of a row or docume
