我刚刚从 Chronicle Queue 4.6.109 升级到 5.16.16。自从升级以来,我注意到在我们所有使用 Chronicle Queue 的服务中都有以下形式的警告:
2018-10-16 16:26:58,524 WARN [main] SCQIndexing 花了 256 时间进行线性扫描,从 379578902 到 379580588 = (0x169ff0ac-0x169fea16)=1686

...
这是真正值得担心的事情还是仅用于(内部)分析?我可以在我的代码中更改什么来消除这些警告,即减少扫描时间(除了将属性chronicle.queue.report.linear.scan.latency 设置为false)?
