Benchmark PR redis#14224
Type: Clean (correct implementation)
Original PR Title: Fix HINCRBYFLOAT removes field expiration on replica
Original PR Description: Fixes redis#14218
Before, we replicate HINCRBYFLOAT as an HSET command with the final value in order to make sure that differences in float precision or formatting will not create differences in replicas or after an AOF restart.
However, on the replica side, if the field has an expiration time, HSET will remove it, even though the master retains it. This leads to inconsistencies between the master and the replica.
To address this, we now use the HSETEX command with the KEEPTTL flag instead of HSET, ensuring that the field’s TTL is preserved.
This bug was introduced in version 7.4, but the HSETEX command was only implemented from version 8.0. Therefore, this patch does not fix the issue in the 7.4 branch, a separate commit is needed to address it in 7.4.
