   Currently you can leave dimensions list empty, then every column, which not specified as metrics, will be indexed as string.
   
   Then you can convert every metric to some legacy format, where you have only one metric field , for example "value" with aggregation longSum. After that you can convert every record to that format
   For example if u have record like this:
   { timestamp : "2131249124" , "hostname":"somehost.com" , "cpu": 23 , "memory": 45 } 
   when you can convert it to format like this:
   { timestamp : "2131249124" , "hostname":"somehost.com" , "metric":"cpu", "value": 23 } 
   { timestamp : "2131249124" , "hostname":"somehost.com" , "metric":"memory", "value" : 45 }
