Numstore

Key Features

Numstore offers a variety of functionalities, ensuring that users can perform critical operations with ease:

• Create: Establish a new variable within the database.
• Delete: Remove a specified variable.
• Get: Retrieve an existing variable.
• Insert: Add data into a variable.
• Read: Access data from a variable.
• Write: Modify data within a variable.
• Remove: Eliminate specific data from a variable.
• Transaction Management: Start, commit, or roll back transactions for enhanced data integrity.
• Database Operations: Close and reopen a database as needed.

Sample Usage

Utilizing Numstore for basic operations is straightforward. The following code snippet demonstrates how to work with a Numstore database:

import numpy as np
import pynumstore as ns

# Basic Operations
with ns.open("mydb") as db:
    # Create or get a variable
    y = db.get_or_create("y", dtype="f32")

    # Initialize dataset
    del y[0:]
    print("Initial State: ", y[0:])

    # Append data
    y.append(np.array([1.0, 2.0, 3.0], dtype=np.float32))
    y.append(np.array([4.0, 5.0, 6.0], dtype=np.float32))
    print("Seed Data: ", y[0:])

    # Insert data
    y.insert(2, np.array([4.0, 5.0, 6.0], dtype=np.float32))
    print("After inner insert: ", y[0:])

    # Modify entries
    y[1:4] = np.array([9.0, 9.0, 9.0], dtype=np.float32)
    print("After overwrite 1: ", y[0:])

    # Remove even indices
    del y[0::2]
    print("End state: ", y[0:])
