Jiannan Wang created BOOKKEEPER-536: ---------------------------------------
Summary: The overhead of ReadAheadCache is too large Key: BOOKKEEPER-536 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-536 Project: Bookkeeper Issue Type: Bug Components: hedwig-server Reporter: Jiannan Wang Fix For: 4.3.0 Testing with 300 bytes per message, we observed that when the presentCacheSize is 128M, while the readAheadCache size is ~800M. Total ratio is 800/128 ~= 6.25 with 5.25 times overhead. So if user sets readAheadCache limit size to 2G, it may consumes maximum about 15G which is too large. -- This message is automatically generated by JIRA.
