MySQL Multi-Process Data Reading

There are several methods to achieve multi-process concurrent data reading in MySQL, such as:

1. Using a MySQL connection pool allows multiple database connections to be managed in the pool. Each process retrieves a connection from the pool and then performs concurrent data read operations. This helps to avoid frequently creating and destroying database connections, thus increasing the efficiency of concurrent data reads.
2. Using transactions: In MySQL, transactions can be used to achieve concurrent reading of data, where multiple processes can read the same data simultaneously but cannot write to it at the same time. Transactions ensure data consistency and concurrency.
3. By using stored procedures, multiple SQL statements can be encapsulated together and executed simultaneously in multiple processes, achieving concurrency in data retrieval operations.
4. Partitioning tables in MySQL allows data to be stored in separate partitions, which can be read simultaneously by multiple processes, improving efficiency for concurrent data retrieval.
5. Utilizing MySQL’s master-slave replication allows for data to be replicated from the master database to the slave database, enabling multiple processes to concurrently read data from different slave databases, facilitating concurrent data reading operations.
