(REST) Different number of records depending on Limit

[smiling_cheetah]

Hello everyone,

Struggling with the following situation and would appreciate any help with:

So there's Rest source with approximately 16k records, which are returned in jsons upon request.

At first I used connector and was able to retrieve all of them (all was good).

Then the source was updated (data structure slightly changed), and things got weird:

using previous settings (limit=100), only 5k records were available. Then during experiments I discovered that by changing limit (10 or 1000), different number of records can be loaded (9k and 1.5k respectively). Now I'm trying to load data with limit=1, but it takes quite a lot of time.

Do you have any suggestions why this might be happening?

I dont have broad experience with REST sources, so got quite confused here

Thanks in advance

UPD: the problem was on the database side
