Mulesoft integration with MongoDB (NOSQL)

Mulesoft with MongoDB is one of the best combinations for big data processing.  MongoDB is leading open source NoSQL database and Mule Soft is leading open source ESB.  This blog is dedicated to integration of Mulesoft with MongoDB .

Installation and configuration of MongoDB

Install MongoDB in your system. I am using window installation of mongoDB. I installed mongoDB 3.0 in my C:\ MongoDB folder. I created data folder to store MongoDB data in C:\data.
start MongoDB server with command

> \MongoDB\Server\3.0\bin\mongod.exe" --dbpath  \ data

MongoDB server started in port –27017 and userId—admin

Now download test data from MongoDB website
 https://raw.githubusercontent.com/mongodb/docs-assets/primer-dataset/dataset.json 
save this to a file named primer-dataset.json.

Import this data into MongoDB with test instance
>  mongoimport --db test --collection restaurants --drop --file \temp\primer-dataset.json

Start mongo editor to test loaded data  
 > MongoDB\Server\3.0\bin\mongo.exe

Run this command to test your database is configured
 > db.restaurants.find().count() 
This will return result.

Configuration of MongoDB connector in Mulesoft

Now configure MongoDB connection in Mule. I am using Mule 3.7
I created small Mule flow to work with MongoDB integration with Mule. This flow getting http request to get data from MongoDB and sending those data in json object.

Now we have restaurants collection in MongoDB , So I use collection  as restaurants.To execute condition query I am using operation – Find object using query map

In Query Attributes I am using  — Create Object manually
