I saw somewhere that spring web client will wait 30 seconds by default till it able to establish a connection. this sound resonable so I just use the default.
However, I have api call using web client with block() that it is actually require to wait the called service to finish a task before sending a response, currently I just intruduce Thread.sleep(2 minutes) and the calling service seems to wait which is good but I need to know how it is configure, I need to make sure the data will be process in full.
No there is no default timeout configured for block and its blocked indefinitely until next its resolved.

There are alternate methods like with timeout to specify the timeout in Spring WebFlux
