groupcache VS cockroach

As shown in the title, DREAMEMO is a distributed cache with out-of-the-box, high-scalability, modular-design features.The groupcache implementation is referenced, and re-structured, specific module differentiation is as follows:

I remember one of the first real-world uses of Go being the groupcache package: https://github.com/golang/groupcache (to serve Chrome downloads, IIRC?)

> comes with a cache filling mechanism. Whereas memcached just says "Sorry, cache miss", often resulting in a thundering herd of database (or whatever) loads from an unbounded number of clients (which has resulted in several fun outages), groupcache coordinates cache fills such that only one load in one process of an entire replicated set of processes populates the cache, then multiplexes the loaded value to all callers.

I read that group cache (https://github.com/golang/groupcache) can be used to sync servers around a key.

I've not tried this myself, but I've seen it suggested to use groupcache (https://github.com/golang/groupcache) to sync your servers.

https://github.com/golang/groupcache is managing distributed caching that addresses thundering herd problem of memcache.

I really enjoyed google's https://github.com/golang/groupcache. Learned both about the language, and quality network application design

golang/groupcache (Go): groupcache is a caching and cache-filling library, intended as a replacement for memcached in many cases.

CockroachDB is an open source distributed SQL database designed for scalability and resilience. While it offers SQL databases, CockroachDB is also compatible with PostgreSQL.

CockroachDB - SQL

For example, when you create a serverless postgres database with a platform like CockroachDB or Neon, you effectively get a connection string with a strong password. Anyone can connect to your database from anywhere so long as they have the right connection string. There are no security settings in these services to change this behavior.

> Yes you can on the android emulator. The biggest issue is compu arch in that case.

I can also download VirtualBox and run all Windows programs, that would mean that all Windows apps are Linux apps?

> Yes you can for the most part

You can't statically link glibc: https://github.com/cockroachdb/cockroach/issues/3392

glibc can break stuff: https://www.gamingonlinux.com/2022/08/valve-dev-understandab...

I had binaries break because the newer version if openssl was put under a slightly different name.

Also, worth noting, if you're already using PostgreSQL (or plan to) you might want to take a look at https://www.cockroachlabs.com/ they have a free tier too and CockroachDB has a PostgreSQL interface.

I know that some projects like cockroach use custom build tools like bazel. But we actually really like to use to be able to build our projects simply with the great go toolchain and don't really aim to dive deep into custom build solutions.

Cockroachdb created a go runtime patch which measures the Grunning time of a goroutine: https://github.com/cockroachdb/cockroach/pull/82356. It doesn't entirely solve the problem though.

Our entire backend is written in Go. We've built a platform that allows other companies to offer automatic data syncing to their customers' data warehouses. Go works great for building distributed systems like this (see K8s). We're not the only ones in the space building data intensive applications with Go. Pachyderm, Pinecone, Cockroach Labs and are all also doing it. We've been quite happy with how Go has worked for us.

I would recommend researching CockroachDB. It does what you're describing natively. The basis of it's design is to distribute data based on geography. It's inexpensive and very simple to install and manage. It's based on Postgres ( but doesn't support all Postgres features). We've been using it for about 1 year and it meets our needs for some of our workload. www.cockroachlabs.com
