Update expiry length of ignite cache

Question

Is there any way to update the expiry legnth for a cache that is already created in ignite? like I create this cache and set expiry policy as 5-day length, after some time I want to make the cache expiry policy to 10-day length.

I prefer to not destroy the cache and recreate it, since the data will be lost if doing so.

Unfortunately you can't update the default expiry time, but you can set the TTL for each row individually:

        var table = ignite.cache("MY_CACHE");
        table.withExpiryPolicy(new CreatedExpiryPolicy(Duration.FIVE_MINUTES))
                .put(1L, 2.0d);
        table.withExpiryPolicy(new TouchedExpiryPolicy(Duration.ONE_HOUR))
                .put(2L, 4.0d);
