Examples with GraphLibrary uk.gov.gchq.gaffer.store.library.GraphLibrary used on opensource projects

Example 1 with GraphLibrary

use of uk.gov.gchq.gaffer.store.library.GraphLibrary in project gaffer-doc by gchq.

the class ExportToOtherGraphExample method simpleExportUsingGraphFromGraphLibrary.

public void simpleExportUsingGraphFromGraphLibrary() {
    // ---------------------------------------------------------
    // Setup the graphLibrary with an export graph
    final GraphLibrary graphLibrary = new FileGraphLibrary("target/graphLibrary");
    final AccumuloProperties exportStoreProperties = new AccumuloProperties();
    // set other store property config here.
    final Schema exportSchema = new Schema.Builder().edge("edge", new SchemaEdgeDefinition.Builder().source("int").destination("int").directed("true").property("count", "int").aggregate(false).build()).type("int", Integer.class).type("true", new TypeDefinition.Builder().clazz(Boolean.class).validateFunctions(new IsTrue()).build()).build();
    graphLibrary.addOrUpdate("exportGraphId", exportSchema, exportStoreProperties);
    final Graph graph = new Graph.Builder().config(StreamUtil.openStream(getClass(), "graphConfigWithLibrary.json")).addSchemas(StreamUtil.openStreams(getClass(), "operations/schema")).storeProperties(StreamUtil.openStream(getClass(), "mockaccumulostore.properties")).build();

    // ---------------------------------------------------------
    showExample(opChain, "This example will export all Edges with group 'edge' to another existing graph 'exportGraphId' using a GraphLibrary." + "We demonstrate here that if we use a GraphLibrary, we can register a graph ID and reference it from the export operation. " + "This means the user does not have to proxy all the schema and store properties when they configure the export operation, they can just provide the ID.");
}

Example 2 with GraphLibrary

use of uk.gov.gchq.gaffer.store.library.GraphLibrary in project gaffer-doc by gchq.

the class ExportToOtherGraphExample method exportToNewGraphBasedOnConfigFromGraphLibrary.

public void exportToNewGraphBasedOnConfigFromGraphLibrary() {
    // ---------------------------------------------------------
    // Setup the graphLibrary with a schema and store properties for exporting
    final GraphLibrary graphLibrary = new FileGraphLibrary("target/graphLibrary");
    final AccumuloProperties exportStoreProperties = new AccumuloProperties();
    // set other store property config here.
    graphLibrary.addProperties("exportStorePropertiesId", exportStoreProperties);
    final Schema exportSchema = new Schema.Builder().edge("edge", new SchemaEdgeDefinition.Builder().source("int").destination("int").directed("true").property("count", "int").aggregate(false).build()).type("int", Integer.class).type("true", new TypeDefinition.Builder().clazz(Boolean.class).validateFunctions(new IsTrue()).build()).build();
    graphLibrary.addSchema("exportSchemaId", exportSchema);
    final Graph graph = new Graph.Builder().config(StreamUtil.openStream(getClass(), "graphConfigWithLibrary.json")).addSchemas(StreamUtil.openStreams(getClass(), "operations/schema")).storeProperties(StreamUtil.openStream(getClass(), "mockaccumulostore.properties")).build();

    // ---------------------------------------------------------
    showExample(opChain, "Similar to the previous example, this example will export all Edges with group 'edge' to another graph using a GraphLibrary. " + "But in this example we show that you can export to a new graph with id newGraphId by choosing any combination of schema and store properties registered in the GraphLibrary. " + "This is useful as a system administrator could register various different store properties, of different Accumulo/HBase clusters and a user could them just select which one to use by referring to the relevant store properties ID.");
