Multiple serious issues with bulk data processing

As you may have seen from my previous post, I am currently uploading a lot of data from an external database into Bubble as a migration to a “nocode” tool.

Because the migrated tables are relational (unlike Bubble) it makes it very difficult to build efficient queries so we needed to populate some extra data.

Over the course of this, I have had to raise a number of bugs on this bulk process that Bubble offers. In short, I have just not been able to do what I needed to do in any kind of reasonable timeframe.

  1. “Fetching List” is constantly displayed when trying to run a bulk action
  2. Unable to search in data tab on large amounts of data - you get “an error occurred”
  3. Bulk operations confirmed as “1 per second” no matter what plan. 250,000 rows of data will therefore take around 70 hours to process.
  4. Field “is empty” does not trigger when the field is a reference to another thing, and that thing has been deleted. You now cannot select those rows as they are both “not empty” and don’t have anything in them.
  5. Same 20 rows are being selected when doing items until # 20 with a filter
  6. Cancelling “ALL” workflows does not work unless you pause them first

Yes, there are a lot of rows but nowhere does it say “don’t use the data tab if you have a large table” or “don’t use bulk actions” etc

Bulk data operations in Bubble are not fit for purpose. You simply have no way at all to process operations on large amounts of data.

This NOT mean that Bubble does not handle volumes of data, it does that well. What it does not do is allow you to manipulate that data from inside the tool.

@malcolm and @josh need to be upfront about the limitations here. And what, if anything, they intend to do about this. I raised issues 5 years ago with the data tab (that are still not fixed) and nothing really seems to have changed since then apart from the really good csv uploader.

These are seriously limiting issues with the platform here - which go well beyond “we do appreciate this feedback on the process” from @eve that I have received last week.

As it stands at the moment, I could never recommend to anyone to use Bubble for large data operations, despite what their technical team will tell you. Look at Xano (or similar) instead.

A sad few weeks for me here, I really thought Bubble was better than this :frowning:


Sadly we can confirm the same issues and this is something that bubble never did well. I would hope this will get more attention as more and more mature products are being built on bubble and these problems become more evident.

If a service line xano offers a faster backend than bubble native, you know you have a problem.


Yeah, we also never recommend using Bubble for large data processing (even medium).
The best way to process it outside the Bubble - and then display data via API/SQL.

As a non technical person, can one of you kindly give a real world example or two of large data processing that Bubble does not do well, so that I can know if it applies to the app I am creating

  1. Migrate some data into Bubble using the (excellnt) CSV importer. Now run something to create Bubble style object relations between the two. So half a Million “book” rows in one Table and 200,000 “author” rows in another. Use a field on one of them to build the Author(s) <> Books relation.

  2. Try to delete 10,000 rows of data

  3. Anything that goes through large amounts of data and updates counts/totals in one go. Try to do it as you go, not rely on “batch” work.

This is interesting. At what point does it become unusable, 5000 rows?

Volume itself is not an issue in Bubble. Half a million rows can be work quite happily even on a lower tier.

The issues crop up when running workflows on those rows in a short period of time.

Bulk Delete is definately an issue though, and I have had problems even at 1000 rows. Don’t try to delete them, add a flag and ignore.


Ok thanks. I have over 450,000 rows of data and a few fields are nested.

In a few months time I will have to query that data to provide some insights for my company.

@NigelG my initial thinking is to have a separate page in my app and create a reporting dashboard type page.


Also I’ve been thinking about if it is slow and an absolute pain in the ass I would just download everything in a CSV and use a 3rd party tool like Excel.

What would you do?

Yeah, it takes a few hours just to bulk delete 5,000 items O.o

You can use the ‘copy from live to dev’ as a trick.

Ahh, good idea. We are not live yet but will note this. Thanks Nigel
