Dimensions - Track 1 vs Track 2

I just wanted to check that there are no limits on the number of dimensions in Track 1 and Track 2 is limited to 256 dimensions - is this correct?

Hi jimking100, thanks for the question.

For the Descriptor Track, yes, submissions are limited to 256 dimensions (columns).

For the Matching Track, the submission is limited to 500,000 rows or less, and note from the Submission Format section that the submission must contain just 3 columns (query_id, reference_id, score).

Hope this helps, good luck!
