--------------------------------------
Summary: Implementation of a Simple, Low-Latency Bounded Shared
Buffer
Key: KAFKA-19134
URL: https://issues.apache.org/jira/browse/KAFKA-19134
Project: Kafka
Issue Type: New Feature
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
Using the shared buffer in the network threads can reduce the GC count (and
elapsed time). The attached patch offers a simple memory pool based on
ConcurrentSkipListMap, and in my small env (1000000000 records), the GC time is
reduced from 127.808 ms to 93.608 ms), and the created bytes are reduced from
40GB to 2GB.
