Side-Eye is massively inspired by DTrace in some of its raw capabilities and the basic idea of dynamic instrumentation. Beyond that, they're very different. At a low level, DTrace is primarily geared towards debugging the kernel, where

Print debugging is the tool most people reach for when they can, but its biggest problem is that you have to change the source code to add the printfs. This is impractical in many circumstances; it generally only works on your local machine

This answer should go to the top.

Very nice work! It seems that Delve is used for inspiration and development, but Golang code is always compiled with frame pointers, I think. Is that right?

Global Tables let database clients in any region read strongly consistent data with region-local latencies. They’re an important piece of the multi-region puzzle — providing latency characteristics that are well suited for read-mostly, non-

Cockroach lets you hash-shard your keys n-ways if you choose to through a feature called hash-sharded indexes ( https://www.cockroachlabs.com/docs/stable/hash-sharded-index... ) That's a trade-off: costlier ran

I think the "default" will evolve with whatever offers the best "serverless" experience in the public clouds. In particular, the cheapest and most granularly-billed option.

Would you mind providing a link to the empty arrays patch? Is this something CRDB should fix?

At GitHub they should be using CockroachDB (:P), a scalable relational database that also supports schema changes. Then their FKs would work just fine (albeit with some performance implications).

Perhaps I could emphasize things differently. FWIW, besides the fact that having a foreign key constraint in that schema would prevent the badness from happening, the even bigger reason why scenarios like that are unlikely is that, realisti

Hi Gab_CV, this is really cool! Congrats! Are you planning on writing any notes about what the port took? You commits are quite clean, but still some narrative would be really interesting.

We have clients using CRDB in pretty constrained environments, and they use it primarily because of the easy administration. I think you'll find it easier to use than a MySQL or Postgres, for example.

Ozgun has done a good job describing some of Citus' benefits; allow me to write the CockroachDB-biased answer. Btw, congrats to all the Citus people on your launch. The highest-level architectural difference is, in my opinion, the fact

I believe this suggestion came up at the time. I think we didn't do anything like it because it would have been more complicated both to implement and to describe, and because it's not particularly common for people to use/ne

Why do you say that they don't hold, exactly? We take our consistency guarantees, and correctness more generally, deadly serious. I think it's fair to say that we did quite well on Aphyr's review; he's found some quite o

I'm not sure how interleaved tables help you with multi-tenancy, but I'd be curious to find out. If, by multi-tenancy, you mean sharing a CRDB cluster between different applications or different instances of the same application,

FWIW, CRDB should be a good fit for people worried about database lock-in. You'd only be "locked in" if you discover that we're much better than the alternatives :) CRDB uses the standard SQL language. Also, CRDB speaks
