+# RFC-53: Use Lock-Free Message Queue Improving Hoodie Writing Efficiency
+
+
+## Proposers
+@zhangyue19921010
+
+## Approvers
+
+## Status
+
+JIRA: https://issues.apache.org/jira/browse/HUDI-3963
+
+
+## Abstract
+
+New option which use Lock-Free Message Queue called Disruptor as inner message queue to improve hoodie writing performance and optimize writing efficiency.
+
+Disruptor linked: https://lmax-exchange.github.io/disruptor/user-guide/index.html#_introduction
+
+
+## Background
+
+Based on master branch, hoodie consumes upstream data (Kafka or S3 files) into the lake is a standard production-consumption model. 
+Currently, hoodie uses `LinkedBlockingQueue` as a inner message queue between Producer and Consumer.
+
+However, this lock model may become the bottleneck of application throughput when data volume is much larger. 
+What's worse is that even if we increase the number of the executors, it is still difficult to improve the throughput.
+
+In other words, users may encounter throughput bottlenecks when writing data into hudi in some scenarios, and increasing the physical hardware scale and parameter tuning cannot solve this problem.
