A question came in today about how many variants are supported per product in CS2007. The answer is somewhat gray:
- There is no practical or enforced limit – so in theory of causing a functional breakage, one can go quite high
- Performance testing was conducted with 250-500 mix on average, with upper limits of 1,000 in the test suites; that can be characterized as the product’s known sweet spot
- How good (or bad) variants will perform is also largely a function of how many variant attributes are present – obviously hundreds of attributes will perform less than tens, etc.
At the end of the day, the best advice I can give – model it and do a simple proof-of-concept exercise. If it works, run with it – as there is no right or wrong answer – just as there is no uniform one-size-fits-all catalog schema.
Hope this helps!
