Code Scripting Approach
Here’s an example of how we might migrate data from a MySQL table to a MongoDB collection using Node.js:
const mysql = require('mysql');
const MongoClient = require('mongodb').MongoClient;
// MySQL connection
const mysqlConnection = mysql.createConnection({
host: 'localhost',
user: 'mysql_user',
password: 'mysql_password',
database: 'mysql_database'
});
// MongoDB connection
MongoClient.connect('mongodb://localhost:27017', (err, client) => {
if (err) throw err;
const db = client.db('your_mongodb_database');
const collection = db.collection('mongodb_collection');
// Query MySQL table
mysqlConnection.query('SELECT * FROM your_mysql_table', (err, results) => {
if (err) throw err;
// Insert data into MongoDB
collection.insertMany(results, (err, result) => {
if (err) throw err;
console.log('Data migrated successfully');
client.close();
});
});
});
Congratulations! for successful Migration of microservice from MySQL to MongoDB.
How to Migrate a Microservice from MySQL to MongoDB
Migrating from MySQL to MongoDB is a strategic decision that can unlock new possibilities for your database infrastructure. MongoDB’s document-based approach offers flexibility and scalability, enabling us to store and manage data more efficiently.
Before doing this migration journey, we must careful planning and consideration of key factors are essential. Understanding the differences between MySQL and MongoDB in terms of data format, query language, schema, and scalability is crucial for a successful migration.
