- You receive HANA alert 'Size of delta storage of column-store tables' (Alert ID 29). The alert is triggered for individual tables.
- In case of mass changes or when there is a resource bottleneck in the system due to high load several occurrences of this alert may occur in parallel.
- In revisions lower then 83 the alert often occurs along with alert 'Record count of delta storage of column-store tables' (Alert ID 19). Both alerts can be processed together since they reflect mostly the same root cause.
Alert ID 19 is going to be suspended in the new Embedded Statistics Server.
