Can you change ExpiryPolicy of existing cache?
Hi running 2.7.0
I created a cache with ModifiedExpiryPolicy
Can we change the policy of the created cache? I know we can do per write
but can we change the default of the existing cache to another policy?

It's not changing the default Expiry Policy, you will have a new Expiry
Policy as long as you use this "cache" object. withExpiryPolivy return
proxy with a new policy, so, all objects that were inserted using this
"cache" object, will have a new policy.

Ok cool. I create my cache using a template and the rest API, but when I
start my application I do...
cache = this.ignite.cache(this.cacheName)
.withExpiryPolicy(new ModifiedExpiryPolicy(new
Duration(timeUnit, this.cacheTtlDuration)));
Can it be changed then at startup as am doing above?
Or at this point I can only do cache.withExpiryPolicy(...).put(key, value);

Hi,
There is no way to change the default policy for the already created cache.
The expiry policy can be changed for all operations on one cache proxy
object using withExpiryPolicy.
