There're a limit for \_id type?

I think that in the past I read some limitation for \_id and I put a limit for my docs with 20 digits, but I like use usually format for UUID in my ORM

Based on this [old thread](https://discuss.elastic.co/t/maximum-length-of-a-specified-document-id/4262) the maximum id length is 512 bytes.
