But as columns are sorted from left > to right, on dropping a column data will again become unorganized as dropped > column data will not be considered during compaction. In these scenarios > complete data need to be sorted again and then submitted to writer step. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
