Yep, I know.
In Wicket 9 it is in fact possible to chain the right stores to do that, which
is pretty nice.
But for now I need a solution for Wicket 8.
Thanks for the help.

Hi.
Is there a way to disable the first level cache in Wicket 8?
Reading the documentation this should be the session attribute named:
„persistentPageManagerData“.
Since this attribute is written in PageStoreManager (specifically
PersistentRequestAdapter) I’m not entirely certain how to accomplish

It would be sufficient for me to run the application from the second

Yes, it seems you need to get rid of this method here -
https://github.com/apache/wicket/blob/53a68caf0b16b6faca07132a7939dedc6184de2f/wicket-core/src/main/java/org/apache/wicket/page/PageStoreManager.java#L498-L502
Beware that this part of Wicket has been reworked in Wicket 9.x and once
you make these changes in 8.x you will need to redo them once you upgrade
to 9.x. Maybe it is a good idea first to migrate to 9.x.

Re: Disable first level cache - session
Hi.
Hmm. Does not seem to remove the session attribute „persistentPageManagerData“,
or lower it’s size.
It still stores a "org.apache.wicket.page.PageStoreManager$SessionEntry“ object
which seems to contain a serialized page.
It is still quite large. That’s my goal, to remove this session data to keep
the session size low.
I have a custom Akka Distributed Data session data store (on Jetty).
The first logging is without the „persistentPageManagerData“, manually removed,
and put back for the second logging.
DDataSessionDataStore$ - Serializing session...done in 0ms
DDataSessionDataStore$ - Session size: 5215
DDataSessionDataStore$ - Serializing session...done in 3ms
DDataSessionDataStore$ - Session size: 89995
My Application looks like this. I’ve used an AbstractPageStore here because it
already does the (de)serialization code needed for the data store.
setPageManagerProvider(new DefaultPageManagerProvider(this) {
override protected def newPageStore(dataStore: IDataStore): IPageStore = {
new AbstractPageStore(getFrameworkSettings().getSerializer(),
dataStore) {
override def getPage(sessionId: String, pageId: Int): IManageablePage
= {
deserializePage(getPageData(sessionId, pageId))
}
override def removePage(sessionId: String, pageId: Int): Unit = {
removePageData(sessionId, pageId)
}
override def storePage(sessionId: String, page: IManageablePage):
Unit = {
storePageData(sessionId, page.getPageId, serializePage(page))
}
override def unbind(sessionId: String): Unit = {}
override def canBeAsynchronous(): Boolean = true
}
}
})
Is it necessary to tweak something in PageStoreManager?

Re: Disable first level cache - session
Hi, You need to create a custom IPageManagerProvider. To make it simpler you can extend from https://github.com/apache/wicket/blob/wicket-8.x/wicket-core/src/main/java/org/apache/wicket/DefaultPageManagerProvider.java and override its #newPageStore(IDataStore) and return an IPageStore that does nothing but delegates to the IDataStore. Then in YourApplication#init() call setPageManagerProvider(yourProvider); On Wed, Apr 14, 2021 at 5:07 PM Bergmann Manfred wrote: > Hi. > > Is there a way to disable the first level cache in Wicket 8? > Reading the documentation this should be the session attribute named: > „persistentPageManagerData“. > Since this attribute is written in PageStoreManager (specifically > PersistentRequestAdapter) I’m not entirely certain how to accomplish that > in a proper way. > It would be sufficient for me to run the application from the second level > cache only. > > > Manfred > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > >
