> In real case, especially in LEFT join, the NULL value will be replaced with hard code like "NULL", "NUL", "N/A" for some purpose.
> To well handle such requirement, it requires to know what string be used to replace in underline data source. And then process it in cube build job with this setting.
> Add one configuration section in cube metadata, for example:
>  "fact_table": "test_kylin_fact", "null_string": [ "NULL", "null" ], "filter_condition": null,
