Selecting database: Always done MySQL but thinking about Redis or Mongo

I am Selecting database: Always done MySQL but thinking about Redis or Mongo

The solution is not very relational at all but just storing documents. Could be MySQL, could be MongoDB och Redis but which one can take the highest number of connections from an API? I am thinking about having 20 webservers in a loadbalancing config. If we are talking about 100 users saving the same amount of json data which one can handle the most reuests?

I recently came across a repository on GitHub with some benchmark results.

You can take a look at the repository here:

https://github.com/webcaetano/mongo-mysql

Results from the tests:

With data size in rows numbers:

  • 10 rows
mysql insert: 1702ms
mysql select: 11ms

mongo insert: 47ms
mongo select: 12ms
  • 100 rows
mysql insert: 8171ms
mysql select: 10ms

mongo insert: 167ms
mongo select: 60ms
  • 1.000 rows
mysql insert: 94813ms (1.58 minutes)
mysql select: 13ms

mongo insert: 1013ms
mongo select: 677ms
  • 10.000 rows

ENGINE=‘MyISAM’ for the MySQL tables:

1000:
mysql insert: 361ms
mongo insert: 938ms

mongo select: 345ms

10000:

You can also test this yourself too:

git clone https://github.com/webcaetano/mongo-mysql.git
cd mongo-mysql
npm install
node index

Hope that this helps!
