one way to improve MTS performance

[zallen]

Hi,friends
I want to use IMDB(In Memory DB) as cache.When the client wants data,it can be fetched from the cache instead of RM(MS SQL server,etc.).In this way the performance can be improved intensively. However i donot find out a good solution to synchronize the cache with RM.
I want to build a MTS component to manage the cache.So what i really want to know is how this component freshes the cache as soon as possible once the RM is changed.

Any suggestions are greatly appreciated! zallen@cmmail.com
Long live of freedom!
