hi everyone,
i am using logstash to sink data from one kafka topic A to another kafka topic B;
whenever A produced data,B will receive it immediately;
everything works fine,but i keep getting this message in the log file: **[2019-12-24T18:34:14,778][INFO ][logstash.outputs.kafka ] Sending batch to Kafka failed. Will retry after a delay. {:batch_size=>1, :failures=>1, :sleep=>0.01}**
