How does InfluxDB handle duplicate points?

The field is FileName.

time (s), fname
1, file1
1, file2
1, file3

I am using influx to log my file uploads. Generally the tags are the same but the fields are different and they can be uploaded quickly. The problem disappears if I turn the precision to us but this is not really a guarantee.

All I need is for influx to log everything I send it, regardless of it being the same time. I can understand if the tag set AND the field set were exactly the same at the same second, but in my case it’s the fields that are different. And I would hate to ruin my index by putting in filenames. The db would be useless after I posted a million files.
