There are few things we need to note in this requirement:
10K rows and 30 columns:
a. What are the data types of these 30 columns? are they complex or simple?
b. What is the approximate size of 10K x 30 column data?
c. Are the mobile devices dedicated for this app? Do we know how much memory all mobile devices contains which uses this app?
For large data, I definitely recommend validating the use case by performing a POC.
If the mobile device is connected, are you going to perform heavy operations to sync the data back to the data source? We definitely need test it.
Microsoft docs reference article: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/offline-apps
There is a statement in the above article:
"These functions are limited by the amount of available app memory because they operate on an in-memory collection. Available memory can vary depending on the device, the operating system, the memory that Power Apps Mobile uses, and the complexity of the app in terms of screens and controls. If you store more than a few megabytes of data, test your app with expected scenarios on the devices on which you expect it to run. You'll generally have 30-70 megabytes of available memory.
The functions also don't automatically resolve merge conflicts when a device comes online. Configuration on what data is saved and how to handle reconnection is up to the maker when writing expressions."
Validate all the use cases before implementing the requirement.
