The company i work for has had some query regarding this matter. They want to check if elasticsearch is capable of limiting the number of unique values allowed in a field.
EX: the fields "source_ip" may only have three unique values, say, 192.168.0.1, 192.168.0.2 and 192.168.0.3.
I searched through the elasitcsearch documentation whether the indices settings, or field mapping supports this, but i could find such possibility.
