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. write logs effectively
  3. key value store for a logging database
  4. storing index for logs
  5. object storage complexity

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
