also keep in mind that perf degrades with the amount of datoms you touch e.g. during query or pull

not with the amount of datoms stored in a DB

indexes are 32-ary trees, so you should notice slight perf degradation when crossing limits of 32, 1024, 32768 and 1M datoms

most databases in the wild are probably in between 1k-32k datoms

so your question about 1M datoms: it’s just one more level in a tree
