Cardinality column (UHC), which is the superelevation cardinality dimension. So how do you deal with such dimensions?Business Layer Processing UHC
For example, the timestamp dimension cardinality may be billions of degrees, can be turned into a date, the base drops to hundreds of thousands of.
Technical layer Processing UHC
Kylin This step through MapReduce, at
will not affect the cube, only the definition of the view needs to be modified. 5, UHC dimension, when a dimension of cardinality is larger, there may be a lot of problems, first of all, may lead to extract fact columns this step caused reducer to appear oom, Second, creating a dimension dictionary tree may cause the dimension dictionary tree to occupy a large amount of memory, in addition to the cube is built slowly and consumes a lot of storage spa
modelsCurrently Kylin only supports star models, and by creating views in hive, we can easily convert snowflake models to star models and even generate a large wide table.D. Frequently changing table field namesKYLIN directly uses the field names in hive as metadata, and if frequent changes to the fact table or the field names of dimension tables result in metadata errors (https://issues.apache.org/jira/browse/KYLIN-1173), Therefore, it is a good way to add a layer of mapping through the view s
