Sometimes when I run a scan \'. I see a continuous flood of data being printed because the table is big. I want to kill the process that print the
scan \'
You could use scan with LIMIT to limit the scan output on shell :
scan 'table', LIMIT => 5
This will show you only 5 rows. You could also press ctlr+s to hold the scan, if you have done a full scan and want to hold on at a specific row.
