Show HN: Home-made database with log-structured writes

7 points

Hi, I'm Marcus. I've spent the last 15 months or so home-coding on a document database, after work, on weekends (every waking hour). My plans for this particular weekend was to implement log-structured writing. It went faster than I thought and the results were faster querying times and fast, append-only writes.

I've been working on this for almost a decade and being this close to the finish line feels surreal. This is my seventh iteration I believe. Everytime I realized I had an architecture built on a bad model I walked away, often in fury, depressed over my weak coding abilities but bouncing back pretty quick. I've gotten to a place where I'm comfortable throwing away months and months of coding. When starting anew I always did it fresh.

I did this from love and facination of search and NLP and to get good at coding. I started late in life as a professional programmer and have always felt the need to catch up with those younger than me. Today I feel like I achieved something.

Here is a demo of a search engine [0] built on ResinDB [1]:
