I am testing this feature : #6015
I executed: HSET test abc {{$value}}
The value size is 4098 characters.
Even though tiering is enabled and tiered_experimental_hash_support is set to true, the data is not being offloaded to SSD.
After 151mb reached, server is throwing an out-of-memory error. Is this expected? Shared Info details here.
