Quick Start

from dbx_py import Database

# Open an in-memory database
db = Database.open_in_memory()

# Or open a file-based database
# db = Database("my_database.db")

# Insert data
db.insert("users", b"user:1", b"Alice")
db.insert("users", b"user:2", b"Bob")

# Get data
value = db.get("users", b"user:1")
print(value.decode('utf-8'))  # Output: Alice

# Count rows
count = db.count("users")
print(f"Total users: {count}")  # Output: Total users: 2

# Delete data
db.delete("users", b"user:2")

# Flush to disk
db.flush()

# Close database
db.close()

Context Manager Support

with Database("my_database.db") as db:
    db.insert("users", b"user:1", b"Alice")
    value = db.get("users", b"user:1")
