What Parameters Should I Pay Attention to When Creating a DB Instance?

If you use a custom parameter template when creating a DB instance, the following specification-related parameters in the custom template are not applied. Instead, the default values are used.

• innodb_buffer_pool_size
• innodb_log_buffer_size
• max_connections
• innodb_buffer_pool_instances
• innodb_page_cleaners
• innodb_parallel_read_threads
• innodb_read_io_threads
• innodb_write_io_threads
• threadpool_size

The value of innodb_parallel_select_count is determined by your instance specifications, instead of the parameter value you configured in the parameter template.
