How to shrink or reorganize the table in HANA.

Dear Experts,

After removing most of the records from the table, I need to release HWM.

What tools in HANA can do it?

For example, in oracle I can use reorganization via brtools or use command "ALTER TABLE <table_name> SHRINK SPACE [COMPACT] [CASCADE];"

Thanks for your attention, I look forward to your comments.

Best Regards

      It's like for all DDL statements: They acquire a table lock and open changes can be escalated to table level locks while the DDL statement is waiting until the open changes are finished. Setting the lock timeout to a small value for the executing transaction can reduce the impact:

      SET TRANSACTION LOCK WAIT TIMEOUT <ms>
