Correct, a common mistake people make is conflating these things. I wrote this several years ago about MongoDB: One thing that helps is if people stop referring to things as SQL / …

Cassandra is not a columnar database, columnar in this sense is about the storage layout. Values for a column are laid next to each other in storage, thus allowing for optimization…

Having used both TSDB and ClickHouse in anger I have some thoughts on this: They are both fantastic engines, I really like that both have made very specific tradeoffs and can be ve…

He doesn't.

Generally these tend to be systems that work with machine generated data, my experience is with sensor data generated by automobiles (automated car efforts). Naive solutions tend t…

I've considered something like that, but instead of trying to figure out crimes, it would produce a score for bills. A corruption score for bills, almost like a facebook for bills …

Honestly, if someone could mitigate the risk for this sort of thing, it's a huge deal. Personally, I hate living in the tech hubs, I'd love to be able to move back to my hometown, …

I am deeply concerned now that my random comment might end up as a VC funded startup.

Most of them I'd wager. Issue is, and it was for me, is that moving out of an area where I can walk down the street and get another great job to an area where the only great job is…

It depends on what you are doing. If you are trying to build something like a database kernel, you want people who have done it before, very specialized. There aren't lots of them …

We aren't going to agree on this, around remote employees. I believe there is value to co-located teams, not everyone agrees and that's fine. The other point is, most startups do n…

If you are bootstrapping, and you are starting a company in an area that does not need the top tier of engineers (which is most of them, regardless of how they talk about hiring th…

Caveat, this comment isn't directed at you (I agree with your comment), but rather the points around what you are saying. One thing that helps is if people stop referring to things…

Correct, there's relatively easy ways to de-risk things. My wife and I dated for 3.5 years and lived together for 2 before we got married. We are in a high income bracket, and both…

No, generally you report to a former engineer, even up to a VP level in most cases, in AWS its usually former engineers until you get to s-level. edit: those people may have ALSO g…

At the higher end of the market (i.e you can get hired at the majors in a senior role or equivalent at a smaller company), I generally see three types of people: I see people that …

Amazon as a company believes margins are an opportunity, either for them, or for someone else. They don't believe in raising prices unless forced to by something external. You aren…

Anecdote incoming, but I've never seen that in 12 years in the industry (asking for an existing slip). And I've worked from everyone from AmaGoogFaceSoft types to HR companies to s…

That's a bit of an oversimplification. Production grade RDBMS systems have far more guard rails, testing and work put in to them than Kafka. It's relatively straight forward to los…

Unfortunately, my employer and team are directly involved in this space. We may not go this way (due to the effort), but its something we may tackle. It's not necessarily new compu…

I'd also add, there's a component of streaming analytics that isn't solved either. One of the points I've tried to make at various companies (we've worked at the same one before) i…

Generally people are looking for a preferred solution, solving the problem, but not in the preferred way is usually not enough. This isn't good or anything (though, sometimes there…

I actually mean reliable. Its probably different now, but at launch, the defaults were fsync'ing every 30 seconds or so. It would literally just apply the change to an memory mappe…

My general feeling is that MongoDb was designed by people who hadn't designed a database before, and marketed to people who didn't know how to use one. Its marketing was pretty sil…

(Guessing you meant to respond to me) Excellent, I'm glad that the "big data" world is starting to look at database literature in terms of how it does execution, as there is much t…
