django and database connection pools when connecting to many databases

If I want my application to connect to potentially hundreds of different databases, what ef开发者_运维技巧fect will this have on database pools?

I'm assuming django has database connection pooling, and if I am connection to 1000 different databases, that will result in allot of memory used up in connection pools no?

Django does not have database connection pooling, it leaves this up to other tools for that purpose (for example pg-bouncer or pg-pool for PostgreSQL). So there is no worry with the number of database you're connecting to in terms of keeping those connections open and using up a bunch of RAM.
