Description: InnoDB table statistics are system tables that contain crucial information about tables using the InnoDB storage engine in MySQL databases. These statistics include data on the number of rows, table size, index distribution, and other parameters that allow database administrators and query optimizers to make informed decisions about the performance and efficiency of database operations. Collecting these statistics is essential for the query optimizer, as it enables it to estimate the cost of different execution plans and choose the most efficient one. Additionally, the statistics are automatically updated as insert, update, and delete operations are performed on the tables, ensuring that the information reflects the current state of the data. In summary, InnoDB table statistics are an essential tool for maintaining and optimizing the performance of databases using this engine, providing a clear and detailed view of the state and structure of the tables.
