It’s 2016. In 1993, I used Microsoft Access to process over 1,000,000 records of data to implement a product profitability model at Staples – on an IBM 486 machine.
We’ve been saddled with a 5000 item limit for views since SharePoint 2010 launched. Oddly, in SharePoint 2007, there was no such limit. When 2010 came out, with its requirements for heavier and beefier hardware, the limit showed up.
I’ve read (well, skimmed) the white papers about why this needs to be. I’ve had long conversations with people in the SharePoint Product Group about the technical debt involved and why it is a “hard” thing to fix. I’ve read the highly visited KB articles about it, like “The number of items in this list exceeds the list view threshold, which is 5000 items” error when you view a SharePoint Online list in Office 365 Enterprise .
Bill Baer ( @williambaer ) has posted some promising messaging about the thresholds (See: Navigating List View Thresholds in SharePoint Server 2016 IT Preview ), but I still don’t see any outward evidence that the limit is going away anytime in the foreseeable future.
I think there have been mixed messages and misinterpreted messages (no blame to Bill). The auto indexing idea which was recently added to Office 365 and comes in SharePoint 2016 (I believe – but I’m not positive) was misconstrued as lifting the 5000 item limit, which it definitely doesn’t.
The 5000 item limit in the UI for lists and libraries is arguably a good thing. There is absolutely NO reason to show more than 5000 items on a view page. Ever. No one can digest that amount of data or make use of it. Views should show just enough information for people to make good decisions about what to do next. (This is a very common mistake in SharePoint information architecture.) There are times when we simply need to have a view which derives from 5000+ items, though. Remember what year it is; 5000 items is a speck, a mote, an iota of data in this Big Data era.
When it comes to calling SharePoint’s APIs, the 5000 item limit simply has to go. It’s a crazy limit in this day and age. I don’t care about all the technical debt talk about it. The SharePoint Product Group should be able to slide a solution underneath, at least on Office 365 – but ideally in on premises versions of SharePoint as well.
That’s the whole point of APIs: you can fix stuff under the hood without breaking any “contracts”. As more and more processing moves off-SharePoint, the 5000 limit is stifling. It’s been a problem for me for years because I live on the client side. I don’t always need all 5000+ items, but I need to know stuff about them: how many items match some criteria, what the sales total is for 12,834 items, how many items fall into a set of groupings, etc.
Whatever approach the Product Group takes shouldn’t matter, as long as they uphold the API contracts. For years they have told us – very rightly – that touching the underlying SQL tables puts us in an unsupported state. As long as we’re calling the APIs, what happens under the covers doesn’t matter. In fact, most of us should care less; that’s Microsoft’s domain and we should leave it to them.
With the new SharePoint Framework (SPX?) coming along – which Ithink is a TREMENDOUSLY good thing – the 5000 item limit is going to be on the minds of every developer who works with SharePoint. There will be no more server side tricks to haul out to cheat your way around this stuff. Those tricks have been reduced in degrees anyway. If SharePoint is to truly be treated as a service (as I firmly believe it should) then it needs to behave like a service in 2016+, not a service in the 1990s – or earlier.
I’ve heard many people – my fellow MVPs included – say that Microsoft will never fix this. There’s no cool Marketing moment in it, no splash they can make at a conference, little to show in the UI for it. But think of the consequences if they DON’T fix it. How long can we continue to believe that we can pump millions of items into a list (which is the true capacity) only to be told that we can only retrieve fewer than 5000 of them from the client side?
Unfortunately, if we assume they won’t fix it or can’t do it right, then the SPX may be doomed, IMO. I’d prefer to believe that they know it has to be fixed and are working on it. As my friend Jeff Shuey ( @shuey ) is always saying “I want to believe!”
