Hi Chris
“Never say never.” However, Coda focuses on enterprise level customers, so performance (and security) are always important. There are limits, obviously, but it depends on many factors, not just the number of rows or number of tables. The number of rows that Coda can comfortable handled has steadily increased since I started using Coda. @Scott_Collier-Weir and his colleagues have built a pack into Xano “with no row limits”.
When I made the comment about limiting rows and docs it had more to do with the structure of the design - I see time and time again that people come with a database design background and try to design their tables that way. 3NF is no longer the be all and end all of database design. Similarly, people bring their experience of Word and Excel documents, including the traditional folder structure to Coda. NO, THAT MAKES NO SENSE!
For me the whole idea behind Coda is to get all your information into one place.
Coda has this document geared towards improving doc performance.
