Only 500MB of storage [same as DigitalOcean's free repo] - which isn't enough

Thank you :)

For anyone who wants to get started with this stack you can do `git clone https://gitlab.com/asad-awadia/kotlin-server-app.git` to get a full maven project with javalin, sqlite with ktorm and jdbi everything setup

love it

do people want a SQL DB over HTTP?

is it because you couldn't find a DB that you could talk to over http[s]?

Mentoring and helping is not predatory

>understand terms?

What do you mean understand terms?

If you need help with programming check out the link in my profile and we can set some time up - it will be more beneficial than buying a book

are you a frontend dev?

Safekeeper to page servers take some time

what happens when the compute server issues a read for something that has made it to the WAL servers but not the page servers?

if storage and compute are separated - how is storage mounted on to the compute? Generally you can attach a volume only to one server at a time

what exactly is the value proposition upon which you can raise millions?

the guy forgot to press shift on the last 1 lol

the fundamental problem with counters is that it does a read-modify-write cycle which is quite harsh on the DB - a better approach is to take advantage that counters are cumulative and we can keep the delta events only and 'merge' them on reads

or just buffer the counters in redis and then flush them out

I have a counters API that does precisely this

Docs are here: cmd+f: 'Counters API now live'

Yeah, saves you from thundering herd problems

https://github.com/ben-manes/caffeine cache does something similar by caching the future that gets returned on look-ups if the value is still being computed

>Fits well in a lot of use cases.

Can you share the use cases? Why Mongo works better than Postgres?

Awesome!

yeah this one was really bad

Apart from the fact that business insider is basically buzzfeed - of course now they think salaries are too high since growth has slowed down

why

actor model has nothing to do with promises

Which consensus algorithm? I don't see raft in the codebase

>GitHub, by design, seeks to be as much of a social network

This is so true - not sure why it isn't getting talked about more - they even have a feed now [which is getting better every few days]

how do you limit bad actors? How do you do rate limit per user?
