I am displaying data from a data store kind in a html table using jsp. I am
trying to delete all records from a Google app engine datastore locally
using following code :
Query gaeQuery = new Query("Book");PreparedQuery pq =
datastore.prepare(gaeQuery);List<Entity> list =
pq.asList(FetchOptions.Builder.withDefaults());for(Entity item : list){
datastore.delete(item.getKey());}
I am able to delete all records by this code. After running this code, I
try to refresh the page to see an empty table. But still there are some
records left which disappears after a second page refresh.
I think this is causing because the stale data remains in the memcache. I
tried googling but not been able to find any solution to clear the memcache
soon after deleting all records of a same kind.
I am looking for a way around to flush/clear the memcache.
