I have a spring-boot application where using webflux and r2dbc-postgres. I have discovered a strange issue when trying to do some db operations in a flatMap().
Code example:
#Transactional
public Mono<Void> insertDummyFooBars() {
return Flux.fromIterable(IntStream.rangeClosed(1, 260).boxed().collect(Collectors.toList()))
.log()
.flatMap(i -> this.repository.save(FooBar.builder().foo("test-" + i).build()))
.log()
.concatMap(i -> this.repository.findAll())
.then();
}
It seems like flatMap can process max 256 elements in batches. (Queues.SMALL_BUFFER_SIZE default value is 256). So when I tried to run the code above (with 260 elements) I've got an exception - TransientDataAccessResourceException and the following message:
Cannot exchange messages because the request queue limit is exceeded; nested exception is io.r2dbc.postgresql.client.ReactorNettyClient$RequestQueueException
There is no Releasing R2DBC Connection after this exception. The pgdb connection/session remains in idle in transaction state and the app is not able to run properly when pool max size is reached and all of the connections are in idle in transaction state. I think the connection should be released even if an exception happened or not.
If I use concatMap instead of flatMap it works as expected - no exception, connection released! It's also ok with flatMap when the elements are less than or equal to 256.
Is it possible to force pgdb connection closure? What should I do If I have lot of db operations in flatMap like this? Should I replace all of them with concatMap? Is there a global solution for this?

I have tried to change the Queues.SMALL_BUFFER_SIZE, and also tried to add a concurrency value to the flatmap. It works when I reduced the value to 255 but I think it is not a good solution.
I got the exception 'MongoWaitQueueFullException' and I realize the number of connections that my application is using. I use the default configuration of Spring boot (2.2.7.RELEASE) with reactive MongoDB (4.2.8). Transactions are used.
Even when running an integration test that basically creates a bit more than 200 elements then groups them (200 groups). 10 connections are used. When this algorithm is executed over a real data-set, this exception is thrown. The default limit of the waiting queue (500) was reached. This does not make the application scalable.
My question is: is there a way to design a reactive application that helps to reduce the number of connections?
This is the output of my test. Basically, it scans all translations of bundle files and them group them per translation key. An element is persisted per translation key.
return Flux
.fromIterable(bundleFile.getFiles())
.map(ScannedBundleFileEntry::getLocale)
.flatMap(locale ->
handler
.scanTranslations(bundleFileEntity.toLocation(), locale, context)
.index()
.map(indexedTranslation ->
createTranslation(
workspaceEntity,
bundleFileEntity,
locale.getId(),
indexedTranslation.getT1(), // index
indexedTranslation.getT2().getKey(), // bundle key
indexedTranslation.getT2().getValue() // translation
)
)
.flatMap(bundleKeyTemporaryRepository::save)
)
.thenMany(groupIntoBundleKeys(bundleFileEntity))
.then(bundleKeyTemporaryRepository.deleteByBundleFile(bundleFileEntity.getId()))
.then(Mono.just(bundleFileEntity));
The grouping function:
private Flux<BundleKeyEntity> groupIntoBundleKeys(BundleFileEntity bundleFile) {
return this
.findBundleKeys(bundleFile)
.groupBy(BundleKeyGroupKey::new)
.flatMap(bundleKeyGroup ->
bundleKeyGroup
.collectList()
.map(bundleKeys -> {
final BundleKeyGroupKey key = bundleKeyGroup.key();
final BundleKeyEntity entity = new BundleKeyEntity(key.getWorkspace(), key.getBundleFile(), key.getKey());
bundleKeys.forEach(entity::mergeInto);
return entity;
})
)
.flatMap(bundleKeyEntityRepository::save);
}

Spring Reactive is asynchronous. Imagine you have 3 items in your dataset. It opens a connection for the save of the first item. But it won't wait for it to finish and use for the second save. Instead, it opens a second connection as soon as possible. Thus you'll end up overloading all the possible connections in the pool.
I've got Component Integration Test suite setup with Citrus Framework. In order to create a mock service for different components. I've been using simple mapping strategy with the help of XPathPayloadMappingKeyExtractor.
The challenge I've got is to create a multiple responses for different soap requests.
I've been struggling to understand the way it's responding. Any experienced person who can help me out on Citrus and Spring please ?
My Context file:
<citrus-ws:client id="ClientEndpoint"
request-url="http://localhost:8085/"/>
<citrus-ws:server id="BS_Customer_Information"
port="8085"
auto-start="true"/>
My Test Method:
#CitrusTest
public void testingServer() {
soap().client(ClientEndpoint)
.send()
.soapAction("urn:RetrieveAddressBookOP_01")
.payload(new ClassPathResource("Requests/Sample1.xml"));
soap().server(BS_Customer_Information)
.receive()
.soapAction("urn:RetrieveAddressBookOP_01");
soap().server(BS_Customer_Information)
.send()
.payload(new ClassPathResource("AtomicResponses/Response1.xml"));
soap().client(ClientEndpoint)
.receive()
.messageType(MessageType.XML);
}
Issue 1: My Soap Client times out and could not get the response
Question 1: Should the server response be parsed into Soap Env and Body ?
Question 2: Why Would it still call go to Channel Endpoint.inbound when I've already defined my response?

You have to add a fork(true) option to the first `soap().client().send()' action because the Http SOAP protocol is synchronous by nature. The first action in your test waits for a synchronous response and blocks the rest of the test case execution.
Obviously your test needs to receive some other messages before that client response with soap().server(). That is why you need to fork the client send action in the first place so the server actions can perform before the client response has arrived.
In general the SOAP components in Citrus automatically handle SOAP Envelope and SOAP body. So you just need to define the pure body content as payload. SOAP Envelope is added automatically.
Hope this is more clear now.
I have a threadgroup with no of threads = 30 and ramp up = 1. I have a single transaction controller inside this thread group. Inside Transaction controller, there is a synchronizing timer set to 5 users per group and also multiple module controllers pointing to different test fragments residing under same test plan. Each of these test fragments contain a transaction controller and a uniform random timer set to 1000ms.
I am trying to execute the script in non gui mode as follows
jmeter -n -t [path of script] -l [path of output file]
Test gets stopped and I see following messages in log file. Not sure why log shows 0 threads when I actually set the thread count to 30.

Please guide me where I am getting wrong. Thanks.
An extra space is present before number of threads. in ThreadGroup. After I delete the space, Its working.
Does #JmsListener use a poller under the hood, or is it message-driven? When testing with concurrency=1, it seems to read one message per second:

2016-06-23 09:09:50.155 INFO 13044 --- [enerContainer-1] c.s.s.core.service.PolicyChangedHandler : Received: 6: This is a test
If it is polling, how do I adjust the polling rate or increase the number of messages read per poll?
If it is message-driven, I don't why it is so slow???
Yes Spring JMSListener uses polling under the hood by default.
See DefaultMessageListenerContainer
See also the default receiveTimeout which is 1s.
The receive timeout for each attempt can be configured through the "receiveTimeout" property. setReceiveTimeout
Set the timeout to use for receive calls, in milliseconds. The default is 1000 ms, that is, 1 second.
NOTE: This value needs to be smaller than the transaction timeout used by the transaction manager (in the appropriate unit, of course). 0 indicates no timeout at all; however, this is only feasible if not running within a transaction manager and generally discouraged since such a listener container cannot cleanly shut down. A negative value such as -1 indicates a no-wait receive operation.
