Issue with CachedPlcConnectionManager in nifi integration
Hi,
I've been working with the CachedPlcConnectionManager on the NiFi integration and I have encountered a problem while looking at issue [ https://github.com/apache/plc4x/issues/623 | #623 ] :
When a successful connection is already stored in the cache and the network connection breaks the connections in the cache are no longer usable, but I have not been able to remove them.
This makes the processor not work until it is manually disabled and enabled.
For the NiFi integration to work properly there should be a way of removing a connection from the cache if it is invalid.
I would appreciate some guidance.
Unai

The only change I did in the nifi integration is to add a timeout in the the CompletableFutures of write/read requests.
Not sure what the maxUseTime changes do.

Could you please summarize which changes these were exactly? Removing the maxUserTime? Because if this is the case, we probably need to have a look at how you are using the ConnectionCache.

I think for that case we have connection state listener which might be
help with such cases.
Best,

Re: Issue with CachedPlcConnectionManager in nifi integration

I have restored maxUserTime.
Sometimes we must hold the connection for a long time. For example, in the
loop retrieve PLC data.
If request timeout the base drive will throw a timeoutException and
cacheManage will close this real connection and set the isConnected of the
leased connection as false.
So we can determine whether the connection is closed in the loop and
automatically connect if it is closed.
If you can merge my New PR. We should remove maxUserTime again.

I removed the maxUseTime. I think it is unnecessary to add request-timeout
