Subject [VOTE] add new store component: JispFilesystemStore
Date Mon, 14 Jan 2002 21:54:03 GMT
Hi Team,
I like to introduce a new component. As always, I did
some fundamental refactoring of the Store components.
(I think, I did never anything else in this project :-/)

New Store Persistence:
I wrote a Jisp <> based
Persistence Store (JispFilesystemStore), which serves cocoon as a swapping 
system. The Persistence Store exists of one datafile and one B-tree indexed
index file which -well- points to this datafile. This is a very
optimal solution, to access quick serialized data. The core developer
of Jisp told me, that Jisp can handle over a million of entries
in one datafile. That should be enough ;-).

Memory Store Refactoring:
I removed this odd FilesystemQueue, etc, which I didn't like from that
day I introduced it ;). Objects are swapped out to the new Store Persistence
if a) Memory Store is full or b) the StoreJanitor forces it, because
Memory is running low in the JVM.

So we have at least only one Thread left in the Store compents, that is 
in the StoreJanitorImpl. But I just overhanded the Store components to the 
jakara-commons community and some people showed interest to develop (with me) this
components further. A Cache with weak references is in discussion actually.

Documentation update:
I updated the related documents, of course.

The only problem is I have the latest running version in my 
workdir and not in the scratchpad. So you're not able to test
the, before I commit the changes. I'm sorry.

I don't suffer from insanity. I enjoy every minute of it.
