Tiered storage not offloading HASH values – Enabled experimental hash support

[jahnavilatha589]

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.

config get tiered*
 1) "tiered_upload_threshold"
 2) "0.1"
 3) "tiered_storage_write_depth"
 4) "50"
 5) "tiered_offload_threshold"
 6) "0.2"
 7) "tiered_min_value_size"
 8) "64"
 9) "tiered_experimental_cooling"
10) "true"
11) "tiered_experimental_hash_support"
12) "true"
