Is this why the native disk storage just keeps growing and does not reduce
after we delete from ignite using SQL?
We are up to 80GB on disk now on some instances. We implemented a custom
archiving feature to move older data out of ignite cache to a PostgresSQL
database but when we delete that data from ignite instance, the disk data
size ignite is using stays the same, and then keeps growing, and
growing....
