Hi,

 

In delete = method, we can only get cache key.  In order to get cache entry = value, we need get Ignite instance and get the = cache.

 

Assume we = already get all of them. Can we get value in the cache by the key? Which = is still valid in cache?

 

Thanks

Shawn

Hi,

 

I have a case which cache entry will be update frequently, = and I only want to persist it when the cache is manually remove(cache = will not change anymore) by me.

 

For this case, It is a good idea to = implement persist logic in delete/deleteAll method while write/writeAll = do nothing?

 

@Override
<= /span>public void = delete<= span lang=3DEN-US = style=3D'font-size:9.0pt;font-family:SimSun;color:#A9B7C6'>(Object = o)
{
    //do nothing, we = never have this operation.
}

 

 

Thanks

Shawn
