I have a term set of every ICD-10 code, which is a taxonomy for categorizing diseases. It is organized in a hierarchical term set and contains approximately 10,000 terms. I created a site and turned on managed navigation and pointed it at my term set.
The result – SharePoint 2013 cannot handle the load and times out. When I now try to navigate to it, I get the following error:
Even worse, there seems to be no way to even manage the site to even delete it – clicking on Manage in the site hierarchy invokes the site and the browser times out!
The only way I could find to delete the site was through SharePoint Designer…
The terms are very hierarchical, e.g. a smart navigation interface wouldn’t load up all 10,000 at once but would have a method to drill down the tree as you move down the navigation hierarchy.
So given that Microsoft is promoting its new catalogue features, imagine an e-commerce company trying to use this feature for their browse – a few thousand SKUs might work, but not millions. When I worked for one of the leading book store chains, we had over 2 million SKU’s in our catalogue – SharePoint 2013 doesn’t seem to be able to easily scale up to this experience using out of the box web parts and navigation.
Another key lesson learned – you can only pick the top of a term set to be the root of your managed navigation…you cannot pick an arbitrary sub-node and start from that point downward:
I can pick the top node here, but not this one:
So I cannot create a single term set and sub-divide it into smaller chunks of navigation – its all or nothing.
