I have a 4 client ZEO cluster that I am setting up a central sessions storage for. I'm wondering if someone can give me a little feedback on what I have done, eg i have a few questions:
1. am i doing this right?
Does not look bad.
thanks :)
Although we use the load balancer to always send the user to the same Zope instance. This way, a centralization of session info is not necessary.
I feel like tying a user to a one instance partially defeats the purpose of a cluster i guess. if that instance goes down the user is inconvenienced.
2. where does the mapping storage store itself on the filesystem? as part of the Data.fs of the root-mounted filestorage?
I probably would try to keep the session info in RAM.
They will get lost when ZEO is restarted -- but that happens (for us) only extremely rarely.
yes the ZEO server is really stable IMO also.
I do not know, what you mean by "Mapping Storage". But, if this is a supported ZODB storage, you should be able to mount one whereever you want.
I have not found any good docs on it other than that it is non-undoable, non-versionable and based on FileStorage. thanks for your feedback. i really appreciate it. <--> george donnelly ~ http://www.zettai.net/ ~ "Quality Zope Hosting" Shared and Dedicated Zope Hosting ~ Zope Servers ~ Zope Websites Yahoo, AIM: zettainet ~ ICQ: 51907738 ~ Sales (USA): 1-866-967-3669
