Hi All, We are trying to delete the child mapping of index. The child mapping was deleted successfully, but disk space is same before and after deletion.

Hi, Even after running optimize, there is no reduction in disk space.

Hi I am also experiencing the same issue . The \_status /\_stats call shows reduction in size , but actual usage on disk is still the same, even after optimize. Any idea why this is happening ?
