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 come across unusual situations where there needs synchronization of data and database schema. When this type of issue occurs then you can start rising a trustworthy 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 tool named Data Comparison, one can synchronize and also associate or equate data of two server databases. In convenience, a user can perform it spontaneously using the command line. You can basically make a report if you want to display the concise outcomes of the data comparison. MySQL Sync can be said as a controlling and friendly to use tool for the synchronization and comparison of MySQL database contents.
Syntax of MySQL Sync
In general, MySQL Sync is a technique to make two databases in MySQL which have equivalent contents. It’s a broad idea that is 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 by using the sync-sql Module in Node.js. Though usual SQL queries are asynchronous in node.js then also if a user require to execute it synchronously then, implementing this sync-sql module one can make it possible. The result set is resumed in synchronized SQL whenever the query is run.
But note that we cannot use this type of module in the production mode since node.js is built up to be asynchronous.
Let us view the installation process of 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 as below:
npm version sync-sql
- Again, you can now just make a folder and supplement it with a file such as index.js using the command that is needed to run:
node index.js
- Succeeding further, now 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, once this is done we can run the file with the command below:
node index.js
Here, 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. Like this way, we can perform the synchronization of MySQL queries in node.js through sync-sql module package.
How does Sync Function Work in MySQL?
MySQL Sync includes certain significant features including Cross-DBMS data evaluation, provides 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 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 also organizing changes with an appropriate and friendly interface.
The software tool prepares users with the throughput capabilities that they require to synchronize the database contents but the cost is much fewer than other equivalent products.
- Clear in implementation: The MySQL Sync can be used by even a fresher or newbie for synchronization and comparison.
- Tranquil synchronization of nominated tables: MySQL Sync tool permits a user to create error-free synchronization writings.
- Capacity to set conventional comparison keys: You can establish comparison keys for comparing tables on the basis of any field.
- Springy auto mapping tool: Allows to customize the way views and tables are balancing together.
- Saving all choices to a project file to re-execute instantly: The project can be applied to execute the services without the need for agreeing all the settings again.
- Controlling the command-line interface for constant integration: This feature helps for automating the work and saving you time.
- Support for modern MySQL versions: We can use MySQL Sync for working 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 backup of one base and after that by 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 which activates a user to synchronize and back up the MySQL databases very swiftly by basically discontinuing the DBMS and doubling its binary files to a dissimilar 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 in great 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 as below:
- Installing and configuring Master-to-Slave replication
- But if you want to create backups then, you need to stop the Slave server.
- Let the MySQL dump or backup all the data records from the memory to the disk.
- Duplicate binary files present 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 preceding to and after executing backups tasks.
In the situation explained above, 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 that is built up in dbForge Studio where we can analyze, equate as well as synchronize the data schemas.
- By doing this, it will be easy to group and filter comparison outputs in the output grid or also produce a report for this specific comparison process using MySQL Sync.
