Hey there, Gophers and DB enthusiasts!
So, I've been diving into Go lately (loving it, by the way!), and I thought, "Why not build something cool to really get my hands dirty?" That's when I stumbled upon go-caskdb, and it sparked an idea. I decided to create my own little file-based database, which I'm calling FileDB. It's been quite the journey, and I wanted to share it with you all!
FileDB is pretty straightforward - it's a key-value store that persists data to disk. Here's what it can do:
Set key-value pairs
Retrieve values by key
Update existing entries
Delete keys (well, kind of - more on that in a sec)
The cool part? It's all stored in a single file! Each entry is encoded with a timestamp, making it easy to track when data was last modified.
Now, I'll be honest - it's not perfect. The delete operation doesn't actually remove data from the file (it just removes the key from memory). And updating a value? It just appends a new entry to the end of the file. So yeah, file size management is definitely something I need to work on!
But man, did I learn a ton building this:
File I/O in Go is pretty sweet. Those os and io packages are powerful!
Encoding and decoding binary data was a fun challenge.
I got to play around with error handling in Go - still getting used to that if err != nil dance!
Designing a simple API made me think hard about usability.
I've got to say, Go's simplicity made this project a blast. Sure, it's not production-ready, but it's been an awesome learning experience.
So, what do you think? Any Go veterans want to tear apart my code? 😅 Or maybe you've built something similar? I'd love to hear your thoughts and suggestions!
Happy coding, everyone!
