excellent, would love to hear more about resources you used while implementing

Re: Show HN: A Database Written in Golang
#22How do you connect to it and actually use it? Does it behave like a SQL database? Row-based? Column-based? Good for analytical workloads? Document store? Redis/memcached database? What are it's strengths or weaknesses? Cool accomplishment in and of itself but hard for anyone here to really give you any criticism or feedback without understanding where it excels and how to work with it.
It does not seem to speak SQL:
$ git clone git@github.com:Sahilb315/AtomixDB.git
Cloning into 'AtomixDB'...
$ cd AtomixDB/
$ go run .
Welcome to AtomixDB
Available Commands:
CREATE - Create a new table
INSERT - Add a record to a table
DELETE - Delete a record from a table
GET - Retrieve a record from a table
UPDATE - Update a record in a table
BEGIN - Begin new transaction
COMMIT - Commit transaction
ABORT - Rollback transaction
EXIT - Exit the program
> create
Enter table name: foo
Enter column names (comma-separated): bar,baz
Enter column types (comma-separated as numbers): 1,2
Enter indexes (format: col1+col2,col3, ... or leave empty):
Table 'foo' created successfully.
> get
Enter table name: foo
Select query type:
1. Index lookup (primary/secondary key)
2. Range query
3. Column filter
Enter choice (1, 2 or 3):
I do find the source to be well organized and quite readable. Especially if you runs the commands in the cli and then trace how they are each implemented.

#23Earlier quoted context omitted.
Yep... but there are dozens of different types of databases out there. There is no way to look at this codebase and give any kind of feedback one way or the other without that understanding, particularly with zero usage examples. Which is what the OP is asking about.
> There is no way to look at this codebase and give any kind of feedback Less than a minute and I know how to use it. It's not complicated. The source code is available and fairly easy. If you can't figure out how to use it in a trivial amount of time, you aren't going to be able to offer anything of value. When did HN go from being about interesting stuff to making bold, ignorant statements like "There is no way to…

#24Someone asked about resources and I ran into this while evaluating embedded db options for a golang project - it's a collection of db components implemented in golang:

yeah as a dev/non-go person don't know how it works either. I assume main.go is where it starts but then what... I see a commands maybe it works by CLI? idk either
Yes it's a CLI REPL, you build and run the binary using the instructions in the README and then create/insert/select from it by typing those commands into the CLI.
Currently there's no way to connect to it like you would a normal SQL db, but you could embed it like you would sqlite.

Hopefully there is a help/man

You're a "dev," but don't seek out test folders/files for use case examples?
Don't let your employer know...

They can be a dev and not want to have to clone and explore the code. There's tons of little bits of friction that're not addressed by the "face" of the repo. E.g. The readme doesn't seem to imply how to connect to this database (the answer is you write to its stdin, it's not socket based).
We're not at work here. Low effort posts are allowed though not encouraged. Implying that making a low effort post somehow makes you not a developer ("you're a 'dev' but don't seem out tests?") is it's own low effort post, while also being hurtful.
Please, let's keep things kind, focused, and clear.
Re: Show HN: A Database Written in Golang
#29I didnt look into it yet but i already wanted to say - cuz of curiosity i build my own graph database in golang :) and i learned alot. so i absolutly understand why you did it and what experiences you probably made on the way :D
congratz !
Re: Show HN: A Database Written in Golang
#30Nice, did you follow a course or any resources to build it? Please share, I have a similar goal. Thank you.
I took a quick glance at the code, I believe it may build upon "Build Your Own Database From Scratch in Go" [0]. The first part of the book is available for free on the author's website, along with information on how to purchase the full book (which includes source code).
I share the same goal and am working through the material after working through Codecrafters' "Build your own SQLite" [1]. Good luck!
I apologize in advance for mistakes (formatting, et cetera). I just registered this account to point you toward resources I found helpful.
