SUMMARY

Currently samples are requested with the original row limit, which tends to be 10k. However, samples should by default return 1k rows. This changes the frontend logic to remove row_limit and row_offset from the requested query object so the backend can use the appropriate defaults. The reason this is done in the frontend is to ensure that it's still possible to paginate samples requests if needed. Also clean up some incorrect types + add __future__ annotations for cleaner python sig types.

AFTER

After the change the samples tab only displays 1k rows

BEFORE

Previously it would request 10k rows if the row limit control was set to 10k:
