Chris Riccomini commented on SAMZA-94:
--------------------------------------
This unit test appears to pass, and looks a lot like your example:
{noformat}
@Test
def testDeleteNotNull {
val something = b(letters(0))
store.put(something, something)
val iterator = store.all
assertTrue(iterator.hasNext)
val entry = iterator.next
assertTrue(Arrays.equals(something, entry.getKey))
assertTrue(Arrays.equals(something, entry.getValue))
assertFalse(iterator.hasNext)
iterator.close()
store.delete(something)
val iterator2 = store.all()
assertFalse(iterator2.hasNext)
iterator2.close()
}
{noformat}
> State management kv-store delete() does not remove key

> Key: SAMZA-94
> URL: https://issues.apache.org/jira/browse/SAMZA-94
> Project: Samza
> Issue Type: Bug
> Components: kv
> Affects Versions: 0.6.0
> Reporter: Alan Li
> Assignee: Chris Riccomini
> Fix For: 0.7.0
>
>
> 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.
