Hi , I have a requirement to read CDC messages which are landed in AWS SQS and give the rwas message to S3 and do some processing and write to maria db. I have done a sample spout which reads messages from SQS and two bolts which are for S3 and DB. I am using BaseRich Spout and bolt and doing reliable emit.
I have a doubt on how the order of the message is guranteed when i write the records to database. I want to write in the same order in which the records are read from queue. Can someone give an example topology code where the order is guranteed while using storm processing. Regards Pradeep S
