--------------------------------
Summary: Introduces the lock-free queue Disruptor instead of
arrayBlockQueue
Key: IOTDB-2493
URL: https://issues.apache.org/jira/browse/IOTDB-2493
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Xinyu Tan
Numerous tests and blogs have shown that Disruptor, a lockless queue, performs
better than arrayBlockQueue, a Java native queue. Since IoTDB makes extensive
use of arrayBlockQueue, it's worth exploring Disruptor to see if it can improve
iOTDB performance.
This job includes but is not limited to:
• Investigate the principles behind Disruptor and do a simple performance
comparison with arrayBlockQueue for an in-group share.
* Replace IoTDB read/write critical path arrayBlockQueue to Disruptor, through
all UT/IT and compare performance differences with profile results
