问题
I am using spring xd My stream looks like below and running tests on 3 node container with 1 admin node with rabbit as transport
aws-s3|processor1|http-client|processor2>queue:readyQueue
I have created below tap.
tap1 aws-s3>s3Queue
tap2 processor1>processorQueue1
tap3 http-client>httpQueue
I run below scenarios in my tests:
Scenario1: 5 files of 200k =1 Million records
concurrency of http-client=70 and processor2=30
I see 900k message s3Queue
I see 889k message processorQueue1
I see 886k message httpQueue
I see 883k message processorQueue2 Messages are lost everywhere and its random
Scenario2:
5 files of 200k =1 Million records and all module concurrency=1
I see 998800 message s3Queue
I see 998760 message processorQueue1
I see 997540 message httpQueue
I see 997530 message processorQueue2
Even this number is random and not consistent
Scenario3
I changed stream as below and concurrency=1 and 5 files of 200k =1 Million records
aws-s3 >testQueue
I get all my messages I run 3 times and no issues.I get all my 1 million messages
scenario4
I changed stream as below and concurrency=1 5 files of 200k =1 Million records
aws-s3 |processor1 >testQueue2
I get all my messages I run 3 times and no issues.I get all my 1 million messages
In scenario4 and scenarion 3 data ingestion is faster and it took 5 min to process 5 million faster and ingestion was faster in rabbit transport queue like 5k msg per sec
In scenario 1 data ingestion was slower even s3 module was pulling the data very slow like 300 to 1000 msg per sec
In scenario 2 s3 pulled data faster but http client was slow like 100 msg per sec but aws-s3 pulled data fast like 3-4k msg per sec.
I am thinking like seeing xd threading is causing issues and i am losing messages.Please can you help me how to solve this issue.
update
Scenario 5
I changed reply-timeout to -1 in http client and then
I lost only 37 msgs
Now again I run 2nd iteration I lost 25000 msgs i see the bellowing containers log when that happened

Updated
I found the issue for message loses when this exception happens i see lot of msg lost.This pattern i tested multiple time.Everytime this exception happens i see msg lost.Also bumping up concurrency makes this issue to occur often.

updated with increasing cache size to 200
I added xml provided by you and increased cache size to 200.This is the way happens when processing 1 million and 80 k messages.Only my http client concurrency is 100 all other is 1 .Slowly processing stopped msg are still there before http-client queue and same count.But msg count in my named channel slowly increasing like 10 msg per minute but its very slow s3-poller|processor|http-client>queue:batchCacheQueue
Msg not getting decreass in queue before http 186174.But slowly msg are coming in to batchCacheQueue
Test case to simulate:
1)I was using spring integration aws-s3 source with a splitter in composite module | processor like xml parsing |http-client with concurrency 100 >named channel.
2)I think file source might also work.Create single file of million records and try to pull this from file.
3)After some 4 to 5 run we see this exception happening
回答1:
Caused by: com.rabbitmq.client.impl.UnknownChannelException: Unknown channel number 23364
We found an issue when channels are churned a lot; you need to increase the channel cache size in the rabbit caching connection factory.
See this answer for a work-around.
I opened a JIRA issue so that the next version of Spring XD will expose this setting by in servers.yml so you don't have to override the bus configuration file.
