ESE Cache 1

[Cstorms]

How often do "dirty pages" from ESE cache get written to transaction logs? What is the mechanism that triggers it? I was curious based on the fact that since RAM is utilized to reduce IO, at what point will these pages be written, I assume its got to be fairly dynamic and fluid as to reduce any form of data loss probability but I have yet to find specific information on it.

Thanks for lookin!

I should say that I have read the below and it explains it a bit, but any further info on the actual cause/timing of these events (I may have just glazed over it)

If it's not a full 1MB of data (constituting a normal TL), Exchange will flush it to a log after 15 minutes.
