🚀 StartDB

An AI-Powered Adaptive Database Management System

Self-optimizing • Cloud-Native • Built from Scratch

🧠 Overview

StartDB is a next-generation experimental database engine that learns from usage patterns and optimizes itself automatically. Unlike traditional databases that require manual tuning, StartDB uses AI to predict query patterns, manage indexes, and adapt to workload changes in real-time.

Think of it as a database with a built-in DBA that works 24/7.

Why StartDB?

Modern applications generate dynamic workloads with constantly changing access patterns. Traditional databases require:

⏰ Manual index creation and maintenance
🔧 Human intervention for optimization
📊 Periodic performance analysis

StartDB automates this entire workflow through intelligent pattern recognition and predictive optimization.

🏛️ Architecture

StartDB's layered architecture with AI-powered optimization

✨ Key Features

🏗️ Core Database Engine (Go)

Custom Storage Engine: Built-from-scratch persistence layer with disk and in-memory support
ACID Transactions: Write-Ahead Logging (WAL) ensures data durability and crash recovery
Concurrent Operations: Goroutine-based architecture for high-throughput parallel queries
Flexible Indexing: B-Tree and hash-based indexes with dynamic creation/deletion
SQL-Like Query Language: Familiar syntax with custom parser implementation

🤖 AI Optimization Layer (TypeScript)

Query Pattern Analysis: Machine learning models identify frequent and slow queries
Predictive Indexing: Automatically recommends and creates indexes based on access patterns
Adaptive Caching: Dynamic cache policies that evolve with workload changes
Performance Prediction: Forecasts query execution time and resource usage
Schema Recommendations: Suggests data model optimizations based on usage

☁️ Cloud-Native Design

Containerized Architecture: Docker-first design for consistent deployment

🚀 Getting Started

Prerequisites

Go 1.21 or higher

Quick Start

1. Clone the Repository

git clone https://github.com/Bhup-GitHUB/startdb.git
cd startdb

2. Build and Run

go build -o bin/startdb ./cmd/startdb
./bin/startdb

3. Basic Usage

Memory Storage (Default):

startdb set user:1 "John Doe"
startdb get user:1
startdb list

Disk Storage (Persistent):

startdb --storage=disk set user:1 "John Doe"
startdb --storage=disk get user:1
startdb --storage=disk list

Custom Data File:

startdb --storage=disk --data=my_database.json set key:1 "Custom file"
startdb --storage=disk --data=my_database.json get key:1

With Write-Ahead Logging (WAL):

# Enable WAL for crash recovery
startdb --storage=disk --wal --data=my_database.json set user:1 "John Doe"
startdb --storage=disk --wal --data=my_database.json get user:1

# Create a checkpoint to truncate WAL
startdb --storage=disk --wal --data=my_database.json checkpoint

# Recover from crash by replaying WAL
startdb --storage=disk --wal --data=my_database.json recover

With Transactions:

# Begin a transaction
startdb --storage=disk begin

# Perform operations within the transaction
startdb --storage=disk set user:1 "John Doe"
startdb --storage=disk set user:2 "Jane Smith"
startdb --storage=disk delete user:3

# Check transaction status
startdb --storage=disk status

# Commit the transaction (makes changes permanent)
startdb --storage=disk commit

# Or rollback the transaction (discard changes)
startdb --storage=disk rollback

With SQL Queries:

# Create a table
startdb --storage=disk sql "CREATE TABLE users (id INTEGER, name TEXT, email TEXT)"

# Insert data
startdb --storage=disk sql "INSERT INTO users VALUES (1, 'John Doe', '[email protected]')"
startdb --storage=disk sql "INSERT INTO users VALUES (2, 'Jane Smith', '[email protected]')"

# Query data
startdb --storage=disk sql "SELECT * FROM users"
startdb --storage=disk sql "SELECT * FROM users WHERE id = 1"

# Update data
startdb --storage=disk sql "UPDATE users SET name = 'John Updated' WHERE id = 1"

# Delete data
startdb --storage=disk sql "DELETE FROM users WHERE id = 2"

Available Commands

set <key> <value> - Store a key-value pair
get <key> - Retrieve a value by key
delete <key> - Remove a key-value pair
exists <key> - Check if a key exists
list - List all keys in the database
checkpoint - Create a checkpoint (truncate WAL)
recover - Recover from crash (replay WAL)
begin - Begin a new transaction
commit - Commit the current transaction
rollback - Rollback the current transaction
status - Show transaction status
sql <query> - Execute a SQL query
version - Show version information

Storage Options

--storage=memory - In-memory storage (default, temporary)
--storage=disk - Disk storage (persistent)
--data=filename.json - Custom data file path
--wal - Enable Write-Ahead Logging for crash recovery
--wal-file=filename.wal - Custom WAL file path

🧪 Testing the Database

Interactive Shell Testing

The easiest way to test StartDB is using the interactive shell:

# Start the interactive shell
startdb shell

# Test basic operations
startdb> set user:1 "John Doe"
startdb> get user:1
startdb> list

# Test transactions
startdb> begin
startdb> set user:2 "Jane Smith"
startdb> status
startdb> commit

# Test SQL queries
startdb> sql CREATE TABLE users (id INTEGER, name TEXT)
startdb> sql INSERT INTO users VALUES (1, 'John')
startdb> sql SELECT * FROM users
startdb> quit

Command Line Testing

Test individual commands:

# Test basic operations
startdb set key1 "value1"
startdb get key1
startdb list

# Test with disk storage
startdb --storage=disk set user:1 "John Doe"
startdb --storage=disk get user:1

# Test with WAL
startdb --storage=disk --wal set user:1 "John Doe"
startdb --storage=disk --wal checkpoint

# Test transactions
startdb begin
startdb set user:1 "John Doe"
startdb commit

# Test SQL
startdb sql "CREATE TABLE users (id INTEGER, name TEXT)"
startdb sql "INSERT INTO users VALUES (1, 'John')"
startdb sql "SELECT * FROM users"

Automated Testing

Create test scripts:

# Create a test script
cat > test_script.txt << EOF
set user:1 "John Doe"
set user:2 "Jane Smith"
list
begin
set user:3 "Bob Johnson"
status
commit
sql CREATE TABLE products (id INTEGER, name TEXT)
sql INSERT INTO products VALUES (1, 'Laptop')
sql SELECT * FROM products
quit
EOF

# Run the test script
Get-Content test_script.txt | startdb shell

Performance Testing

Test with larger datasets:

# Create a performance test
for i in {1..1000}; do
  startdb --storage=disk set "key:$i" "value:$i"
done

# Test concurrent operations
startdb --storage=disk begin
startdb --storage=disk set concurrent:1 "test"
startdb --storage=disk commit
