Customized posting format elasticsearch 6.x 7.x

Hi,

I was looking for a way to introduce my own posting format.
It looks like tht was something possible in 0.9 by using the codec module and the posting_format syntax in the mapping file.
Has it been removed in the next versions? Is there another way (plugins?) to do it?

Thanks

As far as I know this is no longer available and you need to adhere to the standard API.
