Thank you. Yes,i mean no merge job triggered.The 'running OK log' in which file? kylin.log or kylin.out file?
Base the jira https://issues.apache.org/jira/browse/KYLIN-1843 "1)Number of entries of each dimension to hold in memory. ... 2) Number of dimension to hold in memory " These dimensions which in memory will be re-created when Build Dimension Dictionary? Or just create those changed dimensions? I just wanted to know: when create a snapshot of the dimension in the step Build Dimension Dictionary, kylin need to put the entire dimension table into memory? Or is there a mechanism that just put those changed dimensions into memory? If has more than one dimension tables and kylin need to put the entire dimension table into memory, in this step(Build Dimension Dictionary), is it easy to cause memory leaks? 2017-11-09 13:11 GMT+08:00 Billy Liu <[email protected]>: > kylin-server-log4j.properties is used for Kylin process.
