Querying for tag values in a given list
问题 Is there any shortform syntax in influxdb to query for membership in a list? I'm thinking of something along the lines of SELECT * FROM some_measurement WHERE some_tag IN ('a', 'b', 'c') For now I can string this together using OR ed = s, but that seems very inefficient. Any better approaches? I looked through the language spec and I don't see this as a possibility in the expression productions. Another option I was thinking was using the regex approach, but that seems like a worse approach
