Storage Write API functionality doesn't work - UNKNOWN: failed to find stream

[tarasrng]

What happened?

I'm trying to implement a very simple PoC using Storage Write API and test it using the emulator (v0.6.3), but I keep getting this error:

com.google.api.gax.rpc.UnknownException: io.grpc.StatusRuntimeException: UNKNOWN: failed to find stream from projects/test-project/datasets/local-bigquery/tables/local-table/_default

Enabling the debug level doesn't help to find the root cause, container logs have nothing suspicious.

Actual code that uses Storage Write API:

        JSONArray rowContentArray = new JSONArray();
        JSONObject rowContent;
        rowContent = new JSONObject();

        rowContent.put("timestamp", DateTimeFormatter.ISO_INSTANT.format(Instant.ofEpochMilli(timestamp).atOffset(ZoneOffset.UTC)));
        rowContent.put("id", deviceIdentifier);
        rowContent.put("json", objectMapper.writeValueAsString(json));
        rowContent.put("partition", partition);

        rowContentArray.put(rowContent);

        TableSchema tableSchema = TableSchema.newBuilder()
                .addFields(TableFieldSchema.newBuilder()
                        .setName("id")
                        .setType(TableFieldSchema.Type.STRING)
                        .setMode(TableFieldSchema.Mode.NULLABLE)
                        .build())
                .addFields(TableFieldSchema.newBuilder()
                        .setName("timestamp")
                        .setType(TableFieldSchema.Type.TIMESTAMP)
                        .setMode(TableFieldSchema.Mode.NULLABLE)
                        .build())
                .addFields(TableFieldSchema.newBuilder()
                        .setName("json")
                        .setType(TableFieldSchema.Type.JSON)
                        .setMode(TableFieldSchema.Mode.NULLABLE)
                        .build())
                .addFields(TableFieldSchema.newBuilder()
                        .setName("partition")
                        .setType(TableFieldSchema.Type.INT64)
                        .setMode(TableFieldSchema.Mode.NULLABLE)
                        .build())
                .build();
                
                        BigQueryWriteSettings settings = BigQueryWriteSettings.newBuilder()
                .setEndpoint(properties.getGrpcHost())
                .setCredentialsProvider(NoCredentialsProvider.create())
                .setTransportChannelProvider(
                        EnhancedBigQueryReadStubSettings.defaultGrpcTransportProviderBuilder()
                                .setChannelConfigurator(ManagedChannelBuilder::usePlaintext)
                                .build()
                )
                .build();

        bigQueryWriteClient = BigQueryWriteClient.create(settings);
        writer = JsonStreamWriter.newBuilder(parentTable.toString(), tableSchema, bigQueryWriteClient)
                .setExecutorProvider(FixedExecutorProvider.create(Executors.newScheduledThreadPool(100)))
                .setChannelProvider(BigQueryWriteSettings.defaultGrpcTransportProviderBuilder()
                        .setKeepAliveTime(org.threeten.bp.Duration.ofMinutes(1))
                        .setKeepAliveTimeout(org.threeten.bp.Duration.ofMinutes(1))
                        .setKeepAliveWithoutCalls(true)
                        .setChannelsPerCpu(2)
                        .build())
                .setEnableConnectionPool(true)
                .setRetrySettings(retrySettings)
                .build()

        ApiFuture<AppendRowsResponse> future = writer.append(rowContentArray);

BTW the emulator works fine when using older insertAll API.

I would appreciate any help in understanding the root cause and how I can troubleshoot the problem.

What did you expect to happen?

The integration test should run successfully

How can we reproduce it (as minimally and precisely as possible)?

This is a sample project demonstrating the issue:
https://github.com/tarasrng/big-query-emulator-write
Test run command (requires Java 21 installed):
./mvnw clean install

Anything else we need to know?

Actual code:
https://github.com/tarasrng/big-query-emulator-write/blob/main/src/main/java/org/example/bigqueryemulatorwrite/repository/BigQueryRepository.java

Table schema creation:

We are having the same issue. We would very much appreciate this functionlity.

[ismailsimsek]

having same error. this might mean we need to explicitly create the stream first. FYI

after explicitly creating the stream. im getting following error.

[UNAUTHENTICATED: Credentials require channel with PRIVACY_AND_INTEGRITY security level. Observed security level: NONE](https://stackoverflow.com/questions/65359948/unauthenticated-credentials-require-channel-with-privacy-and-integrity-security)

https://stackoverflow.com/questions/65359948/unauthenticated-credentials-require-channel-with-privacy-and-integrity-security

this example might help. in which example stream is created explicitly. instead using default stream. https://cloud.google.com/bigquery/docs/write-api-batch#java
