Hybrid model关于bitmap疑问

Dear all： 文档Hybrid model原文描述引用： *请注意, Hybrid model 不适合 “bitmap” 类型的 count distinct 跨 cube 的二次合并，请务必在查询中带上日期维度. * 疑问： 1. 描述中“不适合”如何理解，是功能不支持，还是计算的结果不能有效保证，或者是功能支持，只是性能不佳？ 2. Bitmap是指精确计算的count distinct吗？ 3. 查询中带有时间维度，是指count distinc查询的时候指定的时间不要跨cube吗？ 请解惑，不胜感激！ SnowLake

I change my vote to -1 as there is a critical bug reported in the segment prunner, which is a new feature in Kylin 2.5, please check KYLIN-3705 . The master branch has the hot fix, so we need to cherry-pick it to 2.5.x branch. We will make the RC2
