Johnny Galatikitis updated IGNITE-12905:
----------------------------------------
Description:
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 QueryKeyValueIterable
2. calls default implementation Spliterators.spliteratorUnknownSize(iterator(),
0)
3. which in turn calls ignite's QueryKeyValueIterable.iterator() call and that
"uses it up" for subsequent calls, i.e. throw IgniteException "Iterator is
already fetched or query was cancelled."
