[jira] [Commented] (CARBONDATA-759) How to check a table's properties?

    [ https://issues.apache.org/jira/browse/CARBONDATA-759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15942277#comment-15942277 ] 

Babulal commented on CARBONDATA-759:
------------------------------------

please try "desc formatted <table_name>"  command . 
In comment column you can find the column type .

MEASURE = Measure type column 
DICTIONARY, KEY COLUMN  = dimension  with Dictionary 
KEY COLUMN  = dimension  with NO Dictionary 

In ##Column Group Information    you can find the COLUMN_GROUPS info .
MDK info is used internally and  only dimensions are used to form it . 

Regards 
Babu
