Crate aurora_db 

Aurora Database

Aurora is an embedded document database with tiered storage architecture. It provides document storage, querying, indexing, and search capabilities while optimizing for both performance and durability.

Key Features

• Tiered Storage: Hot in-memory cache + persistent cold storage
• Document Model: Schema-flexible JSON-like document storage
• Querying: Rich query capabilities with filtering and sorting
• Full-text Search: Built-in search engine with relevance ranking
• Transactions: ACID-compliant transaction support

Quick Start

use aurora_db::{Aurora, Value, FieldType};

#tokio::main async fn main() -> Result<(), Box> { // Open a database let db = Aurora::open(“my_app.db”)?;

// Create a collection db.new_collection(“users”, vec![ (“name”, FieldType::String, false), (“email”, FieldType::String, true), // unique field (“age”, FieldType::Int, false), ]).await?;

// Insert data let user_id = db.insert_into(“users”, vec![ (“name”, Value::String(“Jane Doe”.to_string())), (“email”, Value::String(“jane@example.com”.to_string())), (“age”, Value::Int(28)), ]).await?;

// Query data let users = db.query(“users”) .filter(|f| f.gt(“age”, 21)) .collect() .await?;
