I understand that we can calculate cardinality based on the number of unique combinations of measurement, field key, and tag set. But what actually constitutes a high number? Should we think of it in terms of Big O?

</div>

Can the limit of 1M cardinality be overcome by splitting the data into different buckets (assuming that splitting the data will reduce the series cardinality, i.e. only a certain tag value will appear in a bucket)

I’m trying to wrap my head around how to design a schema in order to keep cardinality as low as possible. I think I understand cardinality, how it is calculated, and what the impact is, but as I see it there are multiple…
