can the number of clients be configured?
d
Postgres server 
max_connections
setting?
a
thanks that did it!
now i'm hitting the limitation of 
"error":"read: connection reset by peer"
probably because of too many concurrent requests
is that a setting that we can tweak too?
d

this doesn't seem to be related to SQL storage.
more to do with HTTP/TCP connections

Cerbos uses a connection pool when connecting to a database. You can configure the connection pool settings by adding a 
connPool
section to the driver configuration.
I suggest you to tweak 
maxIdle
 setting
a
ok let me try that
that didn't have any effect. It's definitely related to too many HTTP connections to the API
the server is just dropping the TCP connection
d
If Postgres drops TCP connections then can you please try 
tcp_keepalives_idle
setting
a
its not Postgres dropping the connection. Its the Cerbos API that is dropping it now.

I see
a
bumping the connPool fixed one bottleneck at the DB level but now i'm reaching another bottleneck at the API
d
Now I got it. Thanks for the explanation.
Copy code
server:
  advanced:
    http:
         ...
    grpc:
         ...
This “advanced” section allow configuring settings of HTTP and GRPC connection. I think the relevant protocol setting is “MaxIdleConnsPerHost”, but it can’t be configured at this moment.

got it. thanks. we might be able to get around this by throttling at the load balancer.
