Internal Behaviour of the MySQL Server

[Lars Werdes]

Hello,

I would like to understand the behaviour of the MySQL Server. What happens if I COMMIT a INSERT into a InnoDB table? Does the server allocate space in the memory (in the ranges of innodb_buffer_pool_size) and then, if scheduler or something begins a new cycle, it will be written to the ibdata-file and the allocated memory can be freed.
Or does the server firstly use the innodb_log_buffer or the innodb_log_file and then ibdata. What happens if either the innodb_log_buffer or the innodb_log_file or both is full? Is there maybe anywhere a picture for an timing overview of this kind of behaviour?

Many thanks in advance!
