Hi All, I have a problem that I'm trying to work out and can't find anything online that may help me.
I have been asked to delete 4K records from a Column Family that has a total of 1.8 million rows. I have been given an excel spreadsheet with a list of the 4K PRIMARY KEY numbers to be deleted. Great, the delete will be easy anyway. But before I delete them I want to take a backup of what I'm deleting before I do, so that if the customer comes along and says they got the wrong numbers then I can quickly restore one or all of them. I have been trying to figure out how I can generate inserts from a select but it looks like this is not possible. I'm using centos and Cassandra 2.11 Does anyone have any ideas of what I can do to generate inserts based on primary key numbers in an excel spreadsheet? Kind Regards, Phil
