Re-explain
- Partition Key: Determines which node stores the data (distribution)
- Clustering Key: Determines the sort order within a partition (organization)
CREATE TABLE events (
user_id UUID,
event_time TIMESTAMP,
event_type TEXT,
data TEXT,
PRIMARY KEY (user_id, event_time, event_type)
);
user_id is the partition keyevent_time and event_type are clustering keys- All events for a user are stored together, sorted by time and type
