> Currently,  Non-windowed group aggregate is earlyFiring at count(1), that is every row will emit a aggregate result. But some times user want config count number (`early firing with count[N]`) , to reduce the downstream pressure. This JIRA. will enable the config of e`earlyFiring` for  Non-windowed group aggregate.
