hi,
I'm trying to delete some records. but select fails without any
exception >> Code does not reach deletePersistAll in both the cases.
All I can see is a CPU spike of 9500 cpu_ms. I do see an exception in
try#2. My query expects 400 records & index is created.
I'm approaching 100% datastore limit.
Try#1 >>
String filter = "symbol == '"+ symbol +"' && date == '"+ now +"'";
Query query = persistManager.newQuery("select key from " +
StorableQuote.class);
query.setFilter(filter);
List<Key> results = (List<Key>) query.execute();
persistManager.deletePersistentAll(results);
Try #2 >>
String filter = "symbol == '"+ symbol +"' && date == '"+ now +"'";
Query query = persistManager.newQuery(StorableQuote.class);
query.setFilter(filter);
List<StorableQuote> results = (List<StorableQuote>) query.execute();
persistManager.deletePersistentAll(results);
Exception from logs >>
com.google.appengine.repackaged.com.google.common.base.FinalizableReferenceQueue
<init>: Failed to start reference finalizer thread. Reference cleanup
will only occur when new references are created.
