Usually - 10k rows is a rough and fuzzy limit for a Coda doc.
There are some workarounds (that come with their pros and cons) but with them I’ve stored upwards of 200,000 rows worth of data - and if you were smart about it it could potentially climb up to the millions.
Though I’d love to stress test it?
Overall though - consider 10k a rough limit and start seeking another solution past that number
