_"Validation Failed: 1: id is too long, must be no longer than 512 bytes but was: 635"_
Is there a way to bypass this limitation ?
(I'm using elasticsearch 5.2)

That limit seems to be hard-coded: [https://github.com/elastic/elasticsearch/blob/5.2/core/src/main/java/org/elasticsearch/action/index/IndexRequest.java#L240](https://github.com/elastic/elasticsearch/blob/5.2/core/src/main/java/org/elasticsearch/action/index/IndexRequest.java#L240)
I wonder why your ids are that long. What are you trying to achieve?

It is not such important.. I just wondered if it possible..
