Definition of MySQL Sync
MySQL Sync refers to MySQL Synchronization process in the database server where query executions happen at an identical time period. Uncertainly, every user working with the databases in MySQL server sometimes comes across unusual situations where data and database schema need synchronization. When this type of issue occurs, you can start raising a reliable tool for database synchronization, which can be used in any difficult situation. For this, MySQL Sync tools are offered that are delivered with dbForge Studio.
With the help of the Data Comparison tool, one can synchronize and associate or equate data of two server databases. Inconvenience, a user can perform it spontaneously using the command line. You can make a report if you want to display the concise outcomes of the data comparison. We can describe MySQL Sync as a controlling and user-friendly tool for synchronizing and comparing MySQL database contents.
Syntax of MySQL Sync
In general, MySQL Sync is a technique to make two databases with equivalent contents in MySQL. It’s a broad idea recognized inversely in replications, clustering, and other applications. Handy backup helps in synchronizing MySQL tables through recovery and backup.
We will run the MySQL Synchronous queries using the sync-sql Module in Node.js. Though usual SQL queries are asynchronous in node.js, if a user is required to execute it synchronously, implementing this sync-sql module can make it possible. The result set is resumed in synchronized SQL whenever the query is run.
However, it’s important to note that using this type of module in production mode is not possible due to the asynchronous nature of Node.js.
Let us view the installation process of the sync-sql module as follows:
- Initially, you need to visit the link Install sync-sql module. After that, you can install this package through the command shown below:
npm install sync-sql- Next, you can check the sync-sql version after the installation of this module using the command prompt and running the command below:
npm version sync-sql- Again, you can create a folder and add a file such as index.js, and then execute the required command to run it.
node index.js- To succeed further, you need to open the MySQL server and make a database, for instance, ‘test’.
- For file index.js

const MySQL = require ('sync-mysql')
const connection = newMySQL ({
host:'localhost',
user:'root',
password:'password',
database:'test'
})
var result = connection.query('SELECT NOW()')
console.log(result)- Now, after completing this step, you can run the file using the following command:
node index.jsHere, you can see that the result contains the current date and time, which is outputted through the NOW() function in MySQL added in the file inde.js above. In this way, we can synchronize MySQL queries in node.js through a sync-sql module package.
How Does Sync Function Work in MySQL?
MySQL Sync includes certain significant features, including Cross-DBMS data evaluation, providing native support for standard data sources, synchronizing and comparing the database data, difference display which is easy to study or view, and so on.
You will find the top causes for implementing Data Sync in MySQL, which are listed below:
- Excellence price/Optimal price: MySQL Sync is a good selection for those who want to compare server databases and their contents and organize changes with an appropriate and friendly interface.
The software tool prepares users with the throughput capabilities required to synchronize the database contents, but the cost is much lower than other equivalent products.
- Clear in implementation: MySQL Sync can be used by even a fresher or newbie for synchronization and comparison.
- Tranquil synchronization of nominated tables: MySQL Sync tool allows users to create error-free synchronization writings.
- Capacity to set conventional comparison keys: You can establish comparison keys for comparing tables based on any field.
- Springy auto-mapping tool: Allows customizing how views and tables balance.
- Saving all choices to a project file to re-execute instantly: The project can be applied to execute the services without needing to agree on all the settings.
- Controlling the command-line interface for constant integration: This feature helps automate the work and saves you time.
- Support for modern MySQL versions: We can use MySQL Sync to work with all the updated versions of the MySQL server.
- Complete control over the synchronization and comparison techniques: Provides full control for flexible data sync and customization.
MySQL synchronizes two server databases using Handy Backup by making a dump or, say, a backup of one base and, after that, renovating it. Hence, a user can conglomerate the MySQL Synchronization with the help of encryption, backup, batch processing, advanced storage selections (like SFTP, an S3 cloud, or replicating to FTPS), etc.
Examples of MySQL Sync
You will find a stimulating approach that activates a user to synchronize and back up the MySQL databases swiftly by discontinuing the DBMS and doubling its binary files to a different place. The explanation for this method is regularly a physical backup since it does not support working with the programming interfaces of the database but delights it as a mutual HDD file. For instance, suppose talking about various businesses, the price of downtime of numerous minutes can output significant losses, and this can be another condition where the MySQL duplication verifies its value.
An example for illustrating a scenario of merging imitation and “cold” or “physical” backups can be explained below:
- Installing and configuring Master-to-Slave replication
- But if you want to create backups, you must stop the Slave server.
- Let the MySQL dump or backup all the data records from the memory to the disk.
- Duplicate binary files in the Slave Server’s database to a secure place.
- You require to re-run the Slave server.
But remember that among many other influential features, Handy Backup may also run third-party scripts and applications before and after executing backups tasks.
In the abovementioned situation, a user can set this MySQL Sync function tool to stop the MySQL server for physical backup and to resume it after the replication is accomplished.
Conclusion
- For MySQL Sync, we can humbly apply our Schema Comparison Tool built up in dbForge Studio to analyze, equate, and synchronize the data schemas.
- Doing this will make it easy to group and filter comparison outputs in the output grid or produce a report for this specific comparison process using MySQL Sync.
