Is this valid this link regard elastic search

Dear all.

i have a some issue with below link :

in this link documentation say join support for SQL please correct me!

Link :- joins supported or not?

That link is related to Opendistro for Elasticsearch which claims to support some joins. I am not familiar with that so would recommend you reach out to that community as it is a third party component.

Hi @Christian_Dahlqvist.

Thank you for reply !!!

here i found some link that mention about this :-

But still i i have confusion , how they can force Elastic search to support something!

Thanks

It is implemented as a separate third party plugin.
