减小了事实表的大小； 便于维度的管理和维护，增加、删除和修改维度的属性时，不必对事实表的大量记录进行改动； 维度表可以为多个事实表同时使用，减少重复工作。 b O M而Segment Dictionary虽然也是用于精确计算 COUNT DISTINCT的字典，但与Global Dictionary不同的是，它是基于一个segment的值构建的，因此不支持跨segments的汇总计算。如果你的cube不是分区的或者能保证你的所有SQL按照partition column进行group by, 那么最好使用Segment Dictionary而不是Global Dictionary，这样可以避免单个字典过大的问题。西双版纳谥荣撂科贸有限公司SO u

After you give your ZIP code, it will then take you through the registration process. Texts are free, and you will continue receiving automatic messages unless you opt-out. v Zl Hello- I have an unusual problem perhaps someone could shed some light on: I have a TR-4 in 29K serial range that functions normally except it will not go back into receive, until after approx 30 second delay, after the mic button is released or the function switch turned back to "SSB". This condition worsens (longer delay) the more you frequently you transmit. The sidetone disappears but T-R relay will not release. I have tried different known-good 6EV7 tubes, have replaced a lot of the coupling / bypass caps in T-R circuits, did resistance / voltage checks, adjusted the VOX / VOX delay controls, tried other tubes in T-R circuit, etc. to no avail. What is real curious about this is that while waiting for it to go back into receive and T-R relay is engaged, IF YOU PULL THE 6EV7 FROM ITS SOCKET THE T-R RELAY STILL DOES NOT RELEASE. I suspect the issue is with the lead that goes from T-R relay coil to pin #1 on 6EV7 (somehow allowing enough leakage to ground?) or could it be the T-R relay coil itself I made sure socket / pins and all are clean on 6EV7.

在未来，Apache Kylin还有可能为特定场景、特定类型的维度量身定制特别的编码方式，如在很多行业，身份证号码可能是一个重要的维度。但是身份证号码由于其特殊性而不能使用整数类型的编码（身份证号码的最后一位可能是X），其高基数的特点也决定了其不能使用Dict编码，在目前的版本中只能使用Fixed_length编码，但显然Fixed_length不能充分利用身份证号码中大部分字节是数字的特性来进行深度编码，因此存在一定程度的存储空间的浪费。A bF
