Ochi is a cost-effective, Loki compatible database for logs.

Build

The build will automatically resolve dependencies listed in build.zig.zon.

zig build

This produces the Ochi executable in zig-out/bin/.

Run

By default Ochi looks for ochi.yaml in the current directory.

zig build run

Specify a custom config file:

TODO: For some reason this doesn't work.

zig build run -- -c ./my-ochi.yaml

Configuration

Example ochi.yaml:

server:
  port: 9012
app:
  maxRequestSize: 4194304 # 4MB

Nice to have:

• Design landing page
• Drop a couple blog posts in there on:
  1. why static allocation is not the best
  2. what is the alternative to static allocations?
  3. chunked buffers as an alternative to ArrayList
  4. write logs effectively
  5. key value store for a logging database
  6. storing index for logs
  7. object storage complexity
  8. ARM matters
  9. opencost integration with Grafana
  10. why we must stay opensource forever
  11. tripwire
  12. why we don't use inverted index and full text search

tiny package movements

• extract structs from store/inmem/block_header.zig
• move data.zig to data/Data.zig
• separate data and data/MemTable packages
• separate index and index/Memtable packages
