Generate a UUID using randomuuid in painless

[Yasser_Ouakil]

Hi,

I need help please,
i want to generate a UUID code with Painless language.
I know that exists something like UUID.randomuuid() in Groovy, but is does not work in Painless.

Thank you !

you cannot use this method, as it is not whitelisted in painless. Can you explain your use-case a bit, what exactly you need to do?

Thank you !

I just want to generate a unique ID for each doc.

if you need this for indexing documents, Elasticsearch can autogenerate one for you, if you omit the id in the index action.
