Simple question really. I have a database. In this database are two measurements, measurementA and measurementB. Both measurements have the same tags, tagA and tagB. Now, suppose measurementA has 100000 points with lots of varying tag values, causing a very high cardinality. At the same time, measurementB has only 100 points with only a couple of tag values and very low cardinality.
My question: does the cardinality of measurementA influence query speed (specifically SELECT queries) on measurementB in any way?
