Chris Riccomini updated SAMZA-94:
---------------------------------
Description:
Sample code snippet:
{noformat}
_realtimeStateStore.put("foo", new HashMap());
KeyValueIterator<String, Map<String, State>> realtimeIterator =
_realtimeStateStore.all();
while (realtimeIterator.hasNext())
{
Entry<String, Map<String, State>> entry = realtimeIterator.next();
System.out.println("read from leveldb: " + entry.getKey() + "=>" +
entry.getValue());
}
realtimeIterator.close();
_realtimeStateStore.delete("foo");
KeyValueIterator<String, Map<String, State>> iter =
_realtimeStateStore.all();
while (iter.hasNext())
{
Entry<String, Map<String, State>> entry = iter.next();
System.out.println("read from leveldb: " + entry.getKey() + "=>" +
entry.getValue());
}
iter.close();
{noformat}
Output:
read from leveldb: foo=>{}
read from leveldb: foo=>null
I would expect that the kv would remove both the key & value on delete so that
subsequent iterators will not return keys that have been deleted.
