Default value of `:timeout`

Client API
1

datomic.client.api documentation NS doc string mentions a common :timeout key, but doesn’t state its default value or values for the functions using it.

We are still experiencing Loading database errors, so I was wondering, whether I can work around those by applying some :timeouts
