spring layer. The described solution uses ThreadLocal for this purpose.
Is it possible to provide this tenantId to th

Hi Frans,
would you mind to explain it
I think i don't understand what you want exactly.
Can you tell me what you want to achieve?
And what your code looks like?

thanks for the answer. I didn't get how does it work within the

We developed a multi-tenant app last year.
But we didn't separate their data into different DB.
Instead, we stored all data in one DB, and add
a [tenant_id] column to all tables to distinguish
which tenant it belong.
I think this is a simpler solution.
