About

Using the library go-mysql, I've setup a proof of concept environment where changes to a MySQL table are reflected into a MongoDB collection

Usage

• Start servers:

docker-compose up mysql-server mongodb-server

• Initialize MySQL table with 3 records

docker-compose run mysql-cli init

• List records from MongoDB collection (should return no records)

docker-compose run mongodb-fetcher

• Initialize mysql-consumer, which will read changes from MySQL server

docker-compose up mysql-consumer

• List records from MongoDB collection (should return 3 records)

docker-compose run mongodb-fetcher

• Insert, update and delete records from MySQL table

docker-compose run mysql-cli 'INSERT INTO mytable(value) VALUES ("Record1"), ("Record2"), ("Another record")'

docker-compose run mysql-cli 'UPDATE mytable SET value="RecordTwo" WHERE value="Record2"'

docker-compose run mysql-cli 'DELETE FROM mytable WHERE value="Record1"'

• List records from MongoDB collection (should return the new set of records)

docker-compose run mongodb-fetcher
