> QueryKeyValueIterable 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
> Priority: Major
> Fix For: 2.8.1
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.query.QueryKeyValueIterable
> {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."
