Hi, ``` Thanks for the reply. So incase if I am applying the simple matching pattern as "*" which ``` will match all index, mapping will be created for indices which might not have that field in the future. Will there be any performance issue in those indices which have mapping but no data ? On Fri, Feb 21, 2014 at 2:20 PM, David Pilato [david@pilato.fr](mailto:david@pilato.fr) wrote: > Not yet.
