Okay, thank you for your answer 🤗 Do you mind to answer to my post here if you have time ? Thank you in advance. > [@Best practices for choosing measurement, tags and fields](https://community.influxdata.com/t/best-practices-for-choosing-measurement-tags-and-fields/32556/11): > > Hello, Is it possible to explain when do you want to store the sensor IDs as a tag or as a field ? If I understood well, if you use it as a tag, you increase your series cardinality (so lower your performance). However, if you use it as a field, you lower your performance if you do a lot of queries with it. For information, I am also using InfluxDB V2.x and I am new to this solution. --- _[View the full topic](https://community.influxdata.com/t/current-forum-activity-from-influxdb-team/57693)._
