Story Points:2
2 methods are synchronized on KafkaLogManager:
- getAppender
- getLagPerPartition
The first one takes time only at init but the second can be a long blocking operation depending on the number of topic/partitions.
The getLagPerPartition is used by the monitoring so it impacts the producer's throughput.
Fix this by using different synchronization object.
