    Other

    • cqlengine: a major improvement on queryset has been introduced. It is a lot more efficient to iterate large datasets: the rows are now fetched on demand using the driver pagination.

    • cqlengine: the queryset len() and count() behaviors have changed. It now executes a "SELECT COUNT(*)" of the query rather than returning the size of the internal result_cache (loaded rows). On large queryset, you might want to avoid using them due to the performance cost. Note that trying to access objects using list index/slicing with negative indices also requires a count to be executed.
