How does Kylin handle data update and delete operations?

There are several ways in which Kylin can handle data updates and deletions.

1. By utilizing Kylin’s Reload feature, data can be updated by simply reloading the Cube. When new data needs to be incorporated, users can easily reload the Cube through the Kylin UI or API, prompting Kylin to recalculate and update the data within the Cube.
2. With Cube’s Build feature, Kylin can also update data by rebuilding the Cube. Whenever data needs to be updated, Kylin can recalculate and update the Cube’s data via the Kylin UI or API.
3. With Streaming Cube, Kylin also supports real-time data updates by pushing data to the Cube in real-time through configuration.
4. Data deletion operation: To delete data, you can use the Kylin UI or API to delete data from the Cube, or delete the corresponding data in the data source and then rebuild the Cube to achieve data deletion.

Overall, Kylin provides multiple ways to handle data updates and deletions, allowing users to choose the most appropriate method based on their specific needs.
