Examples with WriteBatch com.google.cloud.firestore.WriteBatch used on opensource projects

Example 1 with WriteBatch

use of com.google.cloud.firestore.WriteBatch in project java-docs-samples by GoogleCloudPlatform.

the class ManageDataSnippets method writeBatch.

/**
 * Write documents in a batch.
 */
void writeBatch() throws Exception {
    db.collection("cities").document("SF").set(new City()).get();
    db.collection("cities").document("LA").set(new City()).get();
    // [START fs_write_batch]
    // Get a new write batch
    WriteBatch batch = db.batch();
    // Set the value of 'NYC'
    DocumentReference nycRef = db.collection("cities").document("NYC");
    batch.set(nycRef, new City());
    // Update the population of 'SF'
    DocumentReference sfRef = db.collection("cities").document("SF");
    batch.update(sfRef, "population", 1000000L);
    // Delete the city 'LA'
    DocumentReference laRef = db.collection("cities").document("LA");
    batch.delete(laRef);
    // asynchronously commit the batch
    ApiFuture<List<WriteResult>> future = batch.commit();
    // future.get() blocks on batch commit operation
    for (WriteResult result : future.get()) {
        System.out.println("Update time : " + result.getUpdateTime());
    }
// [END fs_write_batch]
}

Example 2 with WriteBatch

use of com.google.cloud.firestore.WriteBatch in project beam by apache.

the class BaseFirestoreIT method listCollections.

@Test
@TestDataLayoutHint(DataLayout.Deep)
public final void listCollections() throws Exception {
    // verification and cleanup of nested collections is much slower because each document
    // requires an rpc to find its collections, instead of using the usual size, use 20
    // to keep the test quick
    List<String> collectionIds = IntStream.rangeClosed(1, 20).mapToObj(i -> helper.colId()).collect(Collectors.toList());
    ApiFutures.transform(ApiFutures.allAsList(chunkUpDocIds(collectionIds).map(chunk -> {
        WriteBatch batch = helper.getFs().batch();
        chunk.stream().map(col -> helper.getBaseDocument().collection(col).document()).forEach(ref -> batch.set(ref, ImmutableMap.of("foo", "bar")));
        return batch.commit();
    }).collect(Collectors.toList())), FirestoreTestingHelper.flattenListList(), MoreExecutors.directExecutor()).get(10, TimeUnit.SECONDS);
    PCollection<String> actualCollectionIds = testPipeline.apply(Create.of("")).apply(getListCollectionIdsPTransform(testName.getMethodName())).apply(FirestoreIO.v1().read().listCollectionIds().withRpcQosOptions(rpcQosOptions).build());
    PAssert.that(actualCollectionIds).containsInAnyOrder(collectionIds);
    testPipeline.run(options);
