Is there any problem to store infinite data in a field? Like “customer id”, “unique id”. I want to store customer actions. I’d like to see customer id in it as a field not a tag.
NOTE: Customer size might be over 25 million. Customer id is an UUID(36 character unique structure.)
Hello @Duck,
You need to think about series cardinality with InfluxDB.
Tags are indexed and fields are not. If you were to write this type of data you should write it in as a field. Whether or not InfluxDB will be able to meet your needs depends on HW are ingest rate.
