setting up a batch sqs consumer

[sankalpGoldcast]

I am targeting to use @SqsListener(queueNames = "${sqs.registration-slow-sqs.queue-name}",maxMessagesPerPoll=100, maxConcurrentMessages=100) to poll for upto a max of 100 messages using a single thread and write them all to database in a single transaction, per my understanding this implementation of sqslistener should use a single thread am I wrong in the assumption and number of thread used = maxConcurrentMessages ?
