Subject Use-case with lots of child nodes
Date Tue, 31 May 2016 10:16:08 GMT
Hi Curator users,

I have a use-case where I need to create a very large number (~70,000)  of child nodes under
a parent. These nodes themselves contain no data and will only have a handful of child nodes






I've read ( there is a limit of
1 MB. But I hit the limit for the getChildren operation around 4 MB. I'm interested in what's
causing the difference in the limit.

To give more detail I have a primary and secondary use-case:

My primary use-case includes having watchers on the children of "/someparentNode" and requesting
getChildren for "/someparentNode/LotsOfChildNodesHere-N" (which only has a couple child nodes).

My secondary use-case would be requesting the children of "/someparentNode", which would be
only occasionally for reporting purposes (which has a lot of child nodes and probably won't
be as much as 70k nodes, but I hit the limit there).

I'm looking for answers for the following questions:

What are the stability issues that you think might occur having lots of nodes under one node,
even if we read them rarely?

Can I reliable use the "jute.maxbuffer" system property on the client in the future?

Looking for answers whether the asymmetry of the default value on client side and on server
side is accidental or intentional.

Any advice is much appreciated.
