-Re: Is it possible to indicate the column scan order when scanning table?
Like a table can contain ttl data and static data without indicating
ttl. So, I want to first scan the columns which have ttl restrictions
and later the static columns. The goal that I want to achieve is to
reduce the data missing due to ttl expiration during the scan.
