Hi,

Ignite has no supported view.
We have no plans to add materialized view support in a meduim term perspective
as it distributed implementation looks too complex and low performant.

  and then ignite can let me create a materialized view to auto upate the count 
number or sum num number 。

  I insert a salelog ：(time,vmcode,product)value('2018-03-30 
14:00:00','21321','2123')

 a materialized view "vmSaleCountRealTime" like select 
date(time),vmcode,count(1) todaySaleCount from salelog group by 
date(time),vmcode

  ignite can auto update the todaySaleCount value  of record 
dt=2018-03-20,vmcode=21321

 Is thera have a plan for  materialized view base logs？
