Find max count for a combination of several fields

Say I have a table with three fields message, environment and function.
I want to count up the records by message, environment and function, and then select the highest scoring row for any combination.
Getting the counts is easy
Table
| summarize count() by message, environment, function
...but how do I get just one row with the top count? My solution so far is to create a new table that tallies the counts, then tally max() by environment, function and then do a join, but this seems like an expensive and complicated workaround.

If I understand your original question correctly, you may want to look into summarize arg_max() as well: https://docs.microsoft.com/en-us/azure/kusto/query/arg-max-aggfunction

Add column of totals pr. field value
