3) try to add some column which well-distributed to dimension ,so it can
uniform distribute all the raw values to every row key.
now , 1024 * 1024 values max in one row key !

The raw measure need encode the column values with dictionary; while
dictionary is not good for ultra high cardinality. That's why it
complaints; You can try something as workaround:
1) cut a big segment into several segments, if you were trying to build a
large data set at once;
2) set "kylin.dictionary.max.cardinality" in conf/kylin.properties to a
bigger value (default is 5000000).

hi all,
I am using 1.5.1 for testing.
when I add the raw expression on one column of module, get the following
error message in log file.
Too high cardinality is not suitable for dictionary -- cardinality:
10886118
my question is
1. does this means that the raw expression only allows limited number of
cardinality ?
2. how to modify configuration for this limited number for raw
expression(measure).
