The intetion is commented at line 164. Repasted it here "Each perm change sequence number will be generated during persistence at sentry store. Use a dump id here". However, as the change for using perisisted delta is still not implemented (SENTRY-1567). So here I will revert to the previous implementation. > On Jan. 6, 2017, 9:41 p.m., kalyan kumar kalvagadda wrote: > > sentry-provider/sentry-provider-db/src/main/java/org/apache/sentry/provider/db/service/persistent/SentryStore.java, > > line 1751 > > <https://reviews.apache.org/r/55246/diff/1/?file=1598226#file1598226line1751> > > > > Is there any reason to call this function here, instead of calling it > > persistUpdate? > > > > It is better to call it side persistUpdate API. > > > > This comment is valid in call the places where > > getLastProcessedPermChangeIDCore is called. The reason to call getLastProcessedPermChangeIDCore here is because, we need to first read the current id of permchange table to ensure the multi-table consistency for concurrent transcation. - Hao ----------------------------------------------------------- This is an automatically generated e-mail.
