> Cube does not use the latest snapshot when build， and this will introduce accuracy problems about data.
> detailed case1:
> the 2020-11-25 snapshot was used by cube between 2020-11-24 and 2020-11-25，but when builded after 2020-11-25, it used the 2020-11-07 snapshot rather than the latest snapshot , see fig1 fig2 fig3
> detailed case2:
> data source from hive changed on 20201201，the code trigger on 20201202. see fig4
> so there should have 2 snapshots, one is before changed from hive ,the other is after. see fig5
> from fig6 we can see that the cubes used the 2020-12-01 snapshot between 20201126 and 20201201; between 20201201 and 20201202, between 20201204 and 20201205; between 20201205 and 20201206; between 20201206and 20201207;
> but from fig7 the cubes used the 2020-12-02 snapshot between 20201202and 20201203; between 20201203 and 20201204; see fig 7
