We want to implement now batch delete operation in scyllaDB using golang. I have search in google as well the git repo which I have mention above. I am not getting any sample how to do.
Can sombody help us with sample code how to do batch delete using golang

  1. Our table is the hourwise parition table which contains 100M data will be there
  2. Seperate script which trigger batch delete in this table
    3 Once batch script started means there is no any insert going to happend.

Could you describe in more detail what is the schema (columns, which columns are partition/clustering keys) of the table? What is the delete pattern: do you want to delete whole partitions, some specific rows?
