Because monolithic applications combine database, client-side interfaces, and server-side application elements in a single executable, they’re difficult to understand, even for their own administrators. Use domain-driven design when creating new microservices by separating microservices via their underlying business functions.

Partitioning is a way in which a database (MySQL in this case) splits its actual data down into separate tables but still gets treated as a single table by the SQL layer. If you don’t have well-designed and small columns for this composite primary key, it could enlarge all of your secondary indexes. Additionally, MySQL 8.0
