An incremental backup stores only the changes made since the last full or incremental backup, reducing the size and time required to perform the backup.

innodb_buffer_pool_size optimizes data caching, and max_connections helps handle concurrent connections, both critical for performance tuning. binlog_format is related to replication, not performance.

MySQL Enterprise Monitor provides a visual dashboard that helps administrators track the health and performance of MySQL databases, offering real-time monitoring and optimization suggestions.

InnoDB tables can store their data in separate .ibd files if the innodb_file_per_table option is enabled. These files contain both the table data and indexes for each table.

MySQL Router can be configured to handle read/write splitting, directing read queries to replicas and write queries to the primary server. This improves read scaling in a MySQL InnoDB Cluster.
