TTL and IMMUTABLE_ROWS

[Serega Sheypak]

Hi, here is my table

CREATE TABLE IF NOT EXISTS cross_id_reference
(
  id1        VARCHAR   NOT NULL,
  id2        VARCHAR   NOT NULL,
   CONSTRAINT my_pk  PRIMARY KEY (id1)
) IMMUTABLE_ROWS=true,  TTL=691200;

Is it ok to set TTL and IMMUTABLE_ROWS at the same time? TTL should delete
expired rows. Will it damage IMMUTABLE_ROWS feature?
