-------------------------------------------
Summary: QueryCursorImpl missing custom spliterator()
implementation
Key: IGNITE-12905
URL: https://issues.apache.org/jira/browse/IGNITE-12905
Project: Ignite
Issue Type: Bug
Components: cache, general
Affects Versions: 2.8
Environment: Windows 10
JDK 1.8.0_172
ignite-core 2.8.0
reactor-core 3.3.3
Reporter: Johnny Galatikitis
We are using apache ignite with reactor-core and since reactors upgrade from
3.2.12 to 3.3.3 {code:java}
org.apache.ignite.internal.processors.cache.QueryCursorImpl.iterator
{code}
is called multiple times. It starts with:
1. calling iterable.spliterator().hasCharacteristics(Spliterator.SIZED), where
iterable is instanceof QueryCursorImpl
2. calls default implementation Spliterators.spliteratorUnknownSize(iterator(),
0)
3. which in turn calls ignite's QueryCursorImpl.iterator() call and that "uses
it up" for subsequent calls, i.e. throw IgniteException "Iterator is already
fetched or query was cancelled."
