Heap is no longer the accepted term for these kinds of tables in MySQL but it is still supported for backwards compatibility. The new accepted term is Memory and as the name suggest, Memory tables store their data directly in memory. Memory tables are used primarily as temporary tables. When you delete a row from a memory table, you do not free up space in the server memory. Space is only freed once the table is deleted.

In MySQL, the maximum number of rows and columns a table can have depends on the storage engine, but generally, a MySQL table can have up to 65,535 columns.

You can create a vast number of tables in a MySQL database, with the practical limit being around 4.3 billion tables per database, though performance may degrade with very high numbers.
How does MySQL work?
MySQL is a relational database management system (RDBMS) that uses Structured Query Language (SQL) to manage and manipulate data stored in tables. It operates on a client-server model, where the MySQL server handles data storage, retrieval, and management, while clients send queries and receive results. Data is organized in structured tables, and relationships between tables are defined using keys. MySQL ensures data integrity and supports transactions, allowing multiple operations to be executed reliably.
