converting database from mysql to mongoDb

Question

is there any easy way to change the database from mysql to mongoDB ?

or better any one suggest me good tutorial do it

Answer 1

I think one of the easiest ways is to export the MySQL database to JSON and then use mongorestore to import it to a MongoDB database.

Step 1: Export the MySQL database to JSON

Load the mysql dump file into a MySQL database if necessary

Open MySQL Workbench and connect to the MySQL database

Go to the Schema viewer > Select database > Tables > right-click on the name of the table to export

Select 'Table Data Export Wizard'

Set the file format to .json and type in a filename such as tablename.json

Note: All tables will need to be exported individually

Step 2: Import the JSON files to a MongoDB using the mongorestore command

The mongorestore command should be run from the server command line (not the mongo shell)

Note that you may need to provide the authentication details as well as the --jsonArray option, see the mongorestore docs for more information

mongoimport -d dbname -u ${MONGO_USERNAME} -p ${MONGO_PASSWORD} --authenticationDatabase admin -c collectionname --jsonArray --file tablename.json

Note: This method will not work if the original MySQL database has BLOBs/binary data.
