Shortcut CMD + S increasing the file size.
Files created within InDesign are increasing in size dramatically with every CMD + S.
It is not the files linked in the document which are 100 % to the ration they are seen and resetting the cache ~/Library>Caches> Adobe Indesign does not have any effect.
macOS Mojave
Version 10.14.5
InDesign CC 2019
14.0.2
To test this we have created a quick document with an Adobe Support Technician Saptam (see image-01). This document is 1.5 MB and when the design elements have been deleted and the file saved CMD +S you can see the file size doesn't go down (see image-02).
It remains at 1.5 MB and only when you go File > Save As through the navigation menu does the file size drop again to 1 MB.
For illustration purposes this is was only a small test whilst on the chat feature to Adobe. The files I was originally working on were for a point-of-sale suite
Totem
3.55 GB (CMD + S)
644.8 MB (FILE > SAVE AS)
Wobbler
1.49 GB (CMD + S)
279.8 MB (FILE > SAVE AS)
A1 Poster
2.46 GB (CMD + S)
281.1 MB (FILE > SAVE AS)
This is just a few examples and there was no difference between the files or image quality/size changes. Just File > Save As. Whilst CMD + S just added to my file as if it was embedding all the document history.
Hope you can help on this issue.

It's because of indd file being a database. To flush all trash data from indd you need to do Save As operation; the file is recreated from zero without trash data, you're correct here.
