Elasticcache scaling up takes time

Hi Team,

I have configured dynamic scaling for elastic cache for 80% memory usage, adding shards.

Configurations : 1- 3 primary 2- 2 replica each 3. cache.r6g.large

When it's triggering up, AWS elastic cache modifying the cluster is taking up. Sometimes more than an hour for 14GB of instance.

The impact is when modifying timeout is happening in the application.

Is there any way to avoid this ?
