I'm not entirely sure I understand. Does this mean the permutations of tags are high, i.e. series count is high? If so, isn't this general problem and advice against all TSDBs? If so, I fully agree, you couldn't/shouldn't make for example IP addresses your tags, potentially creating 2**32*2 series without any other tags, it's rather non-sensical proposal in TSDB. Influx themselves comment that >10M series is likely infeasible. So you need unique tag combinations to be low millions at most. -- ++ytti
