Yes! The results of "select count(*) from {fact_table}" both in hive and
kylin are the same！
but the result of "select sum(4g),sum(wifi) from {fact_table}" in hive is
"295763957458,456897813426"
the result of "select sum(4g),sum(wifi) from {fact_table}" in kylin is
"89605527250,164840037298",
Hi, have you try the parameter `kylin.query.enable-dynamic-column=true` which
can count the column without NULL values.
BRs,
May

Hi, have you queried with "select count(*) from {fact_table}" both in hive and
kylin, and please check they have the same result.
I doubt the segments you have built do not include all your hive data.
Best regards,

大神们好！
请容我慢慢描述我的问题
在kylin使用中，我建立了一个model，暂且叫他 big_int_sum_model，Dimensions有11个，
Measures 有三个 分别是 求count, SUM, SUM, sum 是对 两个bigint字段求和，分别为 sum_4g 和sum_wifi
，用以统计4g总流量和wifi总流量
hive表中的数据有400万，在cube之后，可以从kylin查出数据。
但是出现了一个奇怪的现象：
从 hive表中统计的4g流量总数为 295763957458 ,但是kylin中统计出来的是89605527250，
