Dear,
I have datasets having each different created date. But our cassandra db was consisted of primary key with created data which should be created with inserted time.
After inserting datasets, I want to update real time generated created date with each different created date but I don't know how to update this.
Please someone help me to resovle this.
Regards,
Since the column is part of the primary key then you cannot modify it. It breaks the fundamental purpose of a primary key. By definition it is what makes it unique and determines how the data is partitioned in the cluster.
Updating the values of a primary key (an "upsert" in Cassandra) effectively inserts a new partition because the primary key with the new value does not exist so it just gets created like a normal INSERT. See CQL UPDATE command. Cheers! :)
