MySQL is the all-time number one open source database in the world, and a staple in RDBMS space. DigitalOcean is quickly building its reputation as the developers cloud by providing an affordable, flexible and easy to use cloud platform for developers to work with. MySQL on DigitalOcean is a natural fit, but whatβs the best way to deploy your cloud database? In this post, we are going to compare the top two providers, DigitalOcean Managed Databases for MySQL vs. ScaleGrid MySQL hosting on DigitalOcean.
At a glance β TLDR
ScaleGrid Blog - At a glance overview - 1st pointCompare Throughput
ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads. Read now
ScaleGrid Blog - At a glance overview - 2nd pointCompare Latency
On average, ScaleGrid achieves almost 30% lower latency over DigitalOcean for the same deployment configurations. Read now
ScaleGrid Blog - At a glance overview - 3rd pointCompare Pricing
ScaleGrid provides 30% more storage on average vs. DigitalOcean for MySQL at the same affordable price. Read now
MySQL DigitalOcean Performance Benchmark
In this benchmark, we compare equivalent plan sizes between ScaleGrid MySQL on DigitalOcean and DigitalOcean Managed Databases for MySQL. We are going to use a common, popular plan size using the below configurations for this performance benchmark:
Comparison Overview
ScaleGridDigitalOceanInstance TypeMedium: 4 vCPUsMedium: 4 vCPUsMySQL Version8.0.208.0.20RAM8GB8GBSSD140GB115GBDeployment TypeStandaloneStandaloneRegionSF03SF03SupportIncludedBusiness-level support included with account sizes over $500/monthMonthly Price$120$120
As you can see above, ScaleGrid and DigitalOcean offer the same plan configurations across this plan size, apart from SSD where ScaleGrid provides over 20% more storage for the same price.
To ensure the most accurate results in our performance tests, we run the benchmark four times for each comparison to find the average performance across throughput and latency over read-intensive workloads, balanced workloads, and write-intensive workloads.
Throughput
In this benchmark, we measure MySQL throughput in terms of queries per second (QPS) to measure our query efficiency. To quickly summarize the results, we display read-intensive, write-intensive and balanced workload averages below for 150 threads for ScaleGrid vs. DigitalOcean MySQL:
ScaleGrid MySQL vs DigitalOcean Managed Databases - Throughput Performance Graph
For the common 150 thread comparison, ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads.

In this article I will try to teach how to create a dynamic table in react. Ya I know its quite simple, but this tutorial is for beginners and a beginner should know how to get this kind of stuff done.,You mean let's say you want to generate 3Γ4 table? I am not really sure but you can store rows and columns numbers into variable and based on that generate the table. ,how to add search and sorting in the table
import React, { Component } from 'react'
class Table extends Component {
constructor(props) {
super(props) //since we are extending class Table so we have to use super in order to override Component class constructor
this.state = { //state is by default an object
students: [
{ id: 1, name: 'Wasif', age: 21, email: 'wasif@email.com' },
{ id: 2, name: 'Ali', age: 19, email: 'ali@email.com' },
{ id: 3, name: 'Saad', age: 16, email: 'saad@email.com' },
{ id: 4, name: 'Asad', age: 25, email: 'asad@email.com' }
]
}
}
render() { //Whenever our class runs, render method will be called automatically, it may have already defined in the constructor behind the scene.
return (
<div>
<h1>React Dynamic Table</h1>
</div>
)
}
}
export default Table //exporting a component make it reusable and this is the beauty of react
renderTableData() {
return this.state.students.map((student, index) => {
const { id, name, age, email } = student //destructuring
return (
<tr key={id}>
<td>{id}</td>
<td>{name}</td>
<td>{age}</td>
<td>{email}</td>
</tr>
)
})
}
render() {
return (
<div>
<h1 id='title'>React Dynamic Table</h1>
<table id='students'>
<tbody>
{this.renderTableData()}
</tbody>
</table>
</div>
)
}
renderTableHeader() {
let header = Object.keys(this.state.students[0])
return header.map((key, index) => {
return <th key={index}>{key.toUpperCase()}</th>
})
}
render() {
return (
<div>
<h1 id='title'>React Dynamic Table</h1>
<table id='students'>
<tbody>
<tr>{this.renderTableHeader()}</tr>
{this.renderTableData()}
</tbody>
</table>
</div>
)
