Deleting a column simply produces a tombstone for that column, as far as I know. It’s probably going through all the columns with tombstones and timing out. Compacting more often should help, but maybe Cassandra isn’t the best choice overall for what you’re trying to do.

Those columns are then deleted ( it contains active records list ). When i am trying to execute get_count on that raw i get transaction timeout , even while the raw is empty. I dont see anything in cassandra log on neither node , pending tasks are zero. What could be a reason for that , and how can it be resolved? Best regards Yulian Oifa
