Examples with NoOpEngine org.elasticsearch.index.engine.NoOpEngine used on opensource projects

Example 1 with NoOpEngine

use of org.elasticsearch.index.engine.NoOpEngine in project crate by crate.

the class IndicesService method getEngineFactory.

private EngineFactory getEngineFactory(final IndexSettings idxSettings) {
    final IndexMetadata indexMetadata = idxSettings.getIndexMetadata();
    if (indexMetadata != null && indexMetadata.getState() == IndexMetadata.State.CLOSE) {
        // NoOpEngine takes precedence as long as the index is closed
        return NoOpEngine::new;
    }
    final List<Optional<EngineFactory>> engineFactories = engineFactoryProviders.stream().map(engineFactoryProvider -> engineFactoryProvider.apply(idxSettings)).filter(maybe -> Objects.requireNonNull(maybe).isPresent()).collect(Collectors.toList());
    if (engineFactories.isEmpty()) {
        return new InternalEngineFactory();
    } else if (engineFactories.size() == 1) {
        assert engineFactories.get(0).isPresent();
        return engineFactories.get(0).get();
    } else {
        final String message = String.format(Locale.ROOT, "multiple engine factories provided for %s: %s", idxSettings.getIndex(), engineFactories.stream().map(t -> {
            assert t.isPresent();
            return "[" + t.get().getClass().getName() + "]";
        }).collect(Collectors.joining(",")));
        throw new IllegalStateException(message);
    }
}

Example 2 with NoOpEngine

use of org.elasticsearch.index.engine.NoOpEngine in project crate by crate.

the class PeerRecoveryTargetServiceTests method testClosedIndexSkipsLocalRecovery.
