Hi all, m facing two issues which I believe are co-related though. 1. Kafka source shows high back pressure. 2. Sudden checkpoint failure for entire day until restart.
My job does following thing, a. Read from Kafka b. Asyncio to external system c. Dumping in Cassandra, Elasticsearch Checkpointing is using file system. This flink job is proven under high load, around 5000/sec throughput. But recently we scaled down parallelism since, there wasn't any load in production and these issues started. Please find the status shown by flink dashboard. The github folder contains image where there was high back pressure and checkpoint failure https://github.com/sushantbprise/flink-dashboard/tree/master/failed-checkpointing and after restart, "everything is fine" images in this folder, https://github.com/sushantbprise/flink-dashboard/tree/master/working-checkpointing -- Could anyone point me towards direction what would have went wrong/ trouble shooting?? Thanks & Regards, Sushant Sawant
