Hi, We are using Flink to process click stream data from Kafka and pushing the same in 128MB file in S3.
What is the message processing guarantees with S3 sink? In my understanding, S3A client buffers the data on memory/disk. In failure scenario on particular node, TM would not trigger Writer#close hence buffered data can lose entirely assuming this buffer contains data of last successful checkpointing. -- Thanks, Amit
