I have a project already developed by a developer through freelancer.com. This would be an enhancement to it. So the core concept, is the current app has already loaded from Stage directory to stage table, the coding that is required is parsing the records in the stage table based on the table_name to load into the corresponding target tables. There is a level parallelism that needs to be achieved while doing that.

Hello, I have experience in Node.js and SQL, so I can finish this project fast and on a very high quality. I did take a look into attachments. So taking in mind the way Node.JS works with database transactions there's definitely way to do it correctly not using any additional services. Do you have any tests/stage environment running your app? Please, let me know if you are interested in cooperation. Best regards, Ivan Melnyk

Hi, I used to work for Amazon. I am very good at node.js, performance and databases both sql and nosql. This current task (database migration) can be solved using umzug or db-migrate. Hope this information is helpful for you to decide.
