Example 1 with JdbcSchema

use of org.unipop.jdbc.schemas.jdbc.JdbcSchema in project unipop by unipop-graph.

the class RowController method search.

@SuppressWarnings("unchecked")
protected <E extends Element, R> Iterator<R> search(UniQuery query, Map<JdbcSchema<E>, Select> selects, SelectCollector<JdbcSchema<E>, Select, R> collector) {
    if (bulk.size() != 0) {
        contextManager.batch(bulk);
        bulk.clear();
    }
    MetricsRunner metrics = new MetricsRunner(this, query, selects.keySet().stream().map(s -> ((ElementSchema) s)).collect(Collectors.toList()));
    logger.info("mapped schemas for search, schemas: {}", selects);
    if (selects.size() == 0)
        return EmptyIterator.instance();
    Iterator<JdbcSchema<E>> schemaIterator = selects.keySet().iterator();
    Set<R> collect = selects.values().stream().map(select -> this.getContextManager().fetch(select)).flatMap(res -> collector.parse.apply(schemaIterator.next(), res).stream()).collect(Collectors.toSet());
    metrics.stop((children) -> fillChildren(children, selects));
    logger.info("results: {}", collect);
    return collect.iterator();
}

Example 2 with JdbcSchema

use of org.unipop.jdbc.schemas.jdbc.JdbcSchema in project unipop by unipop-graph.

the class RowController method fetchProperties.

@Override
public void fetchProperties(DeferredVertexQuery uniQuery) {
    SelectCollector<JdbcSchema<Vertex>, Select, Vertex> collector = new SelectCollector<>(schema -> schema.getSearch(uniQuery, schema.toPredicates(uniQuery.getPredicates())), (schema, results) -> schema.parseResults(results, uniQuery));
    Map<JdbcSchema<Vertex>, Select> selects = vertexSchemas.stream().filter(schema -> this.traversalFilter.filter(schema, uniQuery.getTraversal())).collect(collector);
    Iterator<Vertex> searchIterator = this.search(uniQuery, selects, collector);
    Map<Object, DeferredVertex> vertexMap = uniQuery.getVertices().stream().collect(Collectors.toMap(UniElement::id, Function.identity(), (a, b) -> a));
    searchIterator.forEachRemaining(newVertex -> {
        DeferredVertex deferredVertex = vertexMap.get(newVertex.id());
        if (deferredVertex != null) {
            deferredVertex.loadProperties(newVertex);
        }
    });
}

Example 3 with JdbcSchema

use of org.unipop.jdbc.schemas.jdbc.JdbcSchema in project unipop by unipop-graph.

the class JdbcSourceProvider method init.

@Override

    this.contextManager = new ContextManager(configuration);
    this.graph = graph;
    Set<JdbcSchema> schemas = Sets.newHashSet();
    getList(configuration, "vertices").forEach(vertexJson -> schemas.add(createVertexSchema(vertexJson)));
    getList(configuration, "edges").forEach(edgeJson -> schemas.add(createEdgeSchema(edgeJson)));
    return createControllers(schemas, traversalFilter);
