K21– ASE’S KERNEL DESIGN FOR THE 21ST CENTURY – ASE 15.7’s THREADED KERNEL K21

November 29th, 2011 No comments

Basic Difference :

Process Kernel:

Pre-15.7 kernel (except Windows)
Each engine is a separate process

Retained in 15.7 for risk mitigation

Threaded Kernel:

Default kernel for 15.7

Each engine is a thread of a single process

Additional threads for handling I/O, etc.

ASE on Windows has always been thread based
