How to Remove a Entry in cache but do not trigger the erase in cachestore

Question

hi guys,
I meet a really special requirement, like the topic, I have a distribute-cache, when put a object in cache, will tigger save method in cachestore to store it to DB, when remve a entry, will tigger the erase method to delete it from DB, and then I need another operation--which can just remove the entry on cache and won't delete from DB? I checked eviction method, but I think it's for local cache. how could I use it on near-cache or distribute cache.
anyone could help me?
Thanks a lot.
best,
DFJ

Answer 1

let me post my code:
package com.admin.processor;
import java.io.IOException;
import com.tangosol.io.pof.PofReader;
import com.tangosol.io.pof.PofWriter;
import com.tangosol.io.pof.PortableObject;
import com.tangosol.util.InvocableMap;
import com.tangosol.util.processor.AbstractProcessor;
public class ValueEvictor extends AbstractProcessor implements PortableObject {
     @Override
     public Object process(InvocableMap.Entry entry) {
entry.remove(true);
return null;
@Override
public void readExternal(PofReader pofReader) throws IOException {
@Override
public void writeExternal(PofWriter pofWriter) throws IOException {
     public static void main(String[] args) {
          AccountKey key = new AccountKey("Test0015678",24);
          AccountEntity account = new AccountEntity();
          account.setDescription("testDescrtiption");
          account.setName("hello");
          account.setParentID(18);
          account.setKey(key);
          NamedCache namedCache=CacheFactory.getCache(account.getClass().getName());
          //namedCache.put(account.getKey(),account);
          namedCache.invoke(key, new ValueEvictor());
