Fastify framework (performs better than express and other sever frameworks or library)
About tech Stack, I was working in Node.js with MariaDB and Fastify framework (performs better than express and other sever frameworks or library). I used Sequelize as ORM library, it is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. To improve the performance of my operations, I needed to run insert operations in multiple batches and those batches had to run in parallel. Aha! Sound nice, but to how to implement it. After spending ample time of searching I found some solution on how to do it. Thanks to Evan Siroky.
