I don't know any technology that makes the JOINs efficient enough for low latency queries. If you're joining two tables that have billions of rows, you need too much memory and CPU resources in order to be able to map them. Do you

Real OLAP queries usually don't have JOINs. Instead, the data is denormalized at ingestion nad WINDOW, CTE ans subqueries are used at query time.

Your comment is indeed not helpful and prevents people to open-source their work unless they think that it is awesome. This tool may not be great but can inspire similar tools or may be helpful for developers who want to learn how to develo

I love the continuous queries over append-only datasets and it's great that Kafka added support for it. It looks like there is one main contributor ( https://github.com/confluentinc/ksql/graphs/contributor

Ah, interesting. It would be nice to check if the people in this post are actually using React and also if the popularity of React is actually affected by these rants. Also, what about the non-React rule of Apache Foundation?

Then why do they bother the whole React community? Do people sue Facebook just because they use React and they spent hundreds of their lawyers hours in order to prove that there's no violation?

Thanks for the clarification. 1. Do you use Postgresql 9.6 query parallelization ( https://www.postgresql.org/docs/9.6/static/parallel-plans.ht... ) or your own method for processing chunks parallelly? When we

I mentioned about the benchmark repo because I wanted to learn why you usually advertise on the write performance instead of query performance. The benchmark repo shares the results for write performance but not query performance. Later on,

Why do you usually advertise the write performance? Let's say that I have "100+ billion rows (the number in your landing page)", how much time it takes to run a simple GROUP BY query? The benchmark repo doesn't actually

This is part of the joke. It can be true but it's almost impossible to have this kind of distribution among developers.

You know, there is a joke that 90% of the developers think that they're better than average. :)

I thought that this was related with the verification but it looks like a feature of the browser.

Not that I'm aware of. It's tricky because the data storage format, query scan method, data distribution etc. requirements are different for OLTP/OLAP. However you can replicate the data to both OLTP and OLAP database and use

It's in-memory so you also need TBs of memory in order to be able to use it for analytical workloads.
