This is incorrect. Dynamic templates are pretty much the same thing.

You can define a mapping that customizes fields based on wildcards. For instance, you can say that any field matching *_ts is treated as a date field.

That means that as new documents arrive with fields that were never seen before, if those fields end in _ts, they will be properly indexed.

That feels like dynamic field support to me.

It really doesn't need to since you aren't bound to a fixed schema. Just use whatever fields are necessary for your documents and map them to the appropriate types.

This is a typo that has been corrected. dynamic fields is indeed supported!
