about a year ago there was a topic raised in this forum for getting a default ingest pipeline option as described here:
Does someone has any news on this or any alternative?
Background on this question is, to create a time stamp (as it was deprecated in V2 and later removed) without having the option to modify REST calls for inserts. Why one would need this? The application can create/use a date field, but there are transport elements in between which can not be controlled, therefore one wants to know, when the actual application event reaches the elasticsearch node to calculate the delay and statistical distributions.
