Hi, the following log message:
[2020-05-12T18:17:57,071][INFO ][main][GridCacheProcessor] Started cache in recovery mode [name=CO_CO_LINE_NEW, id=1742991829, dataRegionName=default, mode=PARTITIONED, atomicity=ATOMIC, backups=1, mvcc=false]
I have the following questions: 1.What has been done in the startup cache in recovery mode?2.After testing, if the node stops normally (non abnormal shutdown), the recovery process will also be performed during startup. Why?

Hello!Direct IO module is experimental and should not be used unless performance is tested first, in your specific use case.Regards, -- Ilya Kasnacheevпн, 18 мая 2020 г. в 16:47, 38797715 <[email protected] <mailto:[email protected]>>:Hi, If direct IO is disabled, the startup speed will be doubled, including some other tests. I find that direct IO has a great impact on the read performance. 在 2020/5/14 上午5:16, Evgenii Zhuravlev 写道:Can you share full logs from all nodes? вт, 12 мая 2020 г. в 18:24, 38797715 <[email protected] <mailto:[email protected]>>: Hi Evgenii, The storage used is not SSD.

Among them, binary recovery took 4970 seconds. Our question is: 1.Why is the start time so long? 2.Is the current state of ignite, with the growth of single node data volume, the restart time will be longer and longer? 3.Do have any suggestions for optimizing the restart time?
