sorry, I can't change my kylin version casually, because I need to consider 
compatibility with other big data component versions

Hi:


I found that the auto merge feature have a issue on kylin 2.2.0:

https://issues.apache.org/jira/browse/KYLIN-3165


And this issue have been resolved in kylin 2.3.0.


&nbsp;If you want to use the feature of the auto merge, you can upgrade to 
2.3.0 or the latest version.

Hi wenhui:

It??s a strange problem.


Can you provide your Kylin version and Hadoop enviornment? I will try to 
reproduce this.

I know your meaning ,the number of READY segments met the conditions of auto 
merge, but&nbsp; auto merge was not triggered, the picture as follows:

Hi Wenhui,

Only if your number of segments  exceed the Auto Merge Thresholds, the 
independent segments will be merged.


For example: there are 3 segments originally and you build the cube today, so, 
there will be 4 segments totally. But 4 < 7, the 4 segments will not be merged.


If you really do not want there are more segments, you can adjust the Auto 
Merge Thresholds to 1 or 2 days.



BTW: The Retention Threshold may be misleading, it is used to guarantee the 
recent xx days segments will be not merged as the recent segments may be 
refreshed separately.
