Tags should not contain highly variable information.
insert measurement1,method=startLevel count=100
insert measurement2,method=passLevel count=200
insert measurement2,method=otherMethod count=300
...
If method have too many distinct value, memory pressure would occur. if we put tag's value into many fields like this:
insert measurement2 startLevel=100,passLevel=200,otherMethod=300...
What problems will cause?
