Validate Database Consistency with New Relic

Database consistency ensures data accuracy and reliability. Discrepancies between databases cause operational errors. Automated consistency checks reduce manual intervention and prevent data drift.

This guide details automated validation between MySQL and Snowflake using Python and New Relic. The process includes secure database connections, row count retrieval, and real-time monitoring in New Relic.

Part 1 covers:

• Why database consistency is critical for data integrity
• Set up Python for database validation tasks
• Establish secure connections to MySQL and Snowflake

Part 2 covers:

• Automate row count validation to verify data consistency
• Record results in New Relic.
• Create alerts and dashboards in New Relic for real-time monitoring.

Database Consistency Requirements

Database consistency maintains data accuracy across systems. This requirement supports reliable reporting and analytics. Automated validation detects discrepancies in complex environments.

Python Configuration for Database Validation

Install the required libraries before writing the script.

pip install newrelic mysql-connector-python snowflake-connector-python 

sshtunnel cryptography

Connect to Snowflake and MySQL

Secure database connection is the first step. Use SSH tunneling for MySQL. Use private key authentication for Snowflake.

Snowflake Connection

Use the Snowflake Python connector with private key authentication. Configure account, user, and private_key_path in the script.

import snowflake.connector
from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import serialization


with open(PRIVATE_KEY_PATH, 'rb') as key_file:
    private_key = serialization.load_pem_private_key(
        key_file.read(),
        password=PRIVATE_KEY_PASSPHRASE.encode(),
        backend=default_backend()
    )

MySQL Connection

SSHTunnel secures the MySQL data transfer. Configure the SSH and MySQL credentials to establish the connection.

from sshtunnel import SSHTunnelForwarder
import mysql.connector


with SSHTunnelForwarder(
        (ssh_host, ssh_port),
        ssh_username=ssh_user,
        ssh_password=ssh_password,
        remote_bind_address=remote_bind_address
) as tunnel:
    conn = mysql.connector.connect(
        host='127.0.0.1',
        port=tunnel.local_bind_port,
        database=db_name,
        user=db_user,
        password=db_password
    )

With connections established, the validation process begins. Part 2 implements row count validation, logs results in New Relic, and configures alerts and dashboards for proactive database consistency monitoring.
