How to reset the IDENTITY column count?

auser85

After accumulating many updates to a delta table,

like,

keyExample bigint GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1),

my identity column values are in the hundreds of millions. Is there any way that I can reset this value through vacuuming or some other option?

The docs mention the following operations are not allowed:

  • PARTITIONED BY an identity column
  • UPDATE an identity column

Delete column is not there so you could drop it and recreate? I'd try that one out.
