vdb - a database system implemented in rust

A basic database system that takes ideas from Entity Component Systems and relational databases.

Run example with

cargo run --example notebook

State of the project

• no dependencies except for serde and chrono
• loads and saves
• add/update/delete key/value pairs
• search for keys/values

Planned

• incremental updates to the save files
  • not calling Vdb::save() will not lose data
• model relationships between stored keys, like foreign keys
• speed improvements
  • separate store for each key
  • indexes
  • partitions
• use of enums instead of &str for keys
• use builder pattern to query database
• bigger & smaller comparisons (a > b)
• create more examples
• remove dependency on serde
  • custom more compact text format
• configuration of storage
  • ~/.config, /var/, custom
• cleanup api

Further in the future

• allow access from multiple threads
• client-server architecture
• binary data storage (with or without serde)
• tooling for schema upgrades
• diesel integration
