[jira] [Commented] (CASSANDRA-6538) Provide a read-time CQL function to display the data size of columns and rows

["Prajakta Bhosale (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-6538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14282474#comment-14282474 ] 

Prajakta Bhosale commented on CASSANDRA-6538:
---------------------------------------------

Yes even I agree, It would be useful in my scenario : 
I am trying to copy the columnfamily data to .csv files using "COPY TO" command: for records > "7 lakh" cassandra node going down without copying the data into .csv file.
So we decided to copy only required columns instead of complete table, which allow me to copy records > 7lakh without node failure.
If we will come to know the size of columns it will help us to decide number of columns to copy in .csv using "COPY TO" command.
