Show HN: A Database Written in Golang

#1

Post by Sahil121 »

Recently created a minimal persistent relational database in Go. Main focus was on implementing & understanding working the of database, storage management & transaction handling. Use of B+ Tree for storage engine(support for indexing), managing a Free List (for reusing nodes), Support for transactions, Concurrent Reads. Still have many things to add & fix like query processing being one of the main & fixing some bugs

Repo link - https://github.com/Sahilb315/AtomixDB

Would love to hear your thoughts

How 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.

This looks like a good exploratory project!

One thing I’d add to the readme is an example of how you’d use the database in an example application. From the docs, it’s clear that this isn’t a sql database (yet?), so it would be good to have an example to see how to use the database.

It might also be nice to have a description of what happens when you insert or get a record, so others can learn from the code too. Or can you comment here about what your favorite part of the code is? What did you figure out that you didn’t know before? If you’re using the project to learn about databases, what have you learned so far?

I think this clearly describes what was the goal.

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.
