I'm little confused with the mapping deprecation, I read here:
I'm creating a new app using the last 5.6 elastic and I have dynamic template mapping defined like in logstash here:
According to the documentation "default" is deprecated in 6.0 so If I use it in 5.6 I'll have deprecation warning when I'll upgrade!
I prefer to go the correct way now, so I have nothing to do later. But the problem is I don't find in the doc what to use to have the equivalent? What is the correct way to go?
Thanks for any help.
