getDatabaseAdminStubSettingsBuilder()
public DatabaseAdminStubSettings.Builder getDatabaseAdminStubSettingsBuilder()Returns the DatabaseAdminStubSettings.Builder that will be used to build the SpannerRpc. Use this to set custom RetrySettings for individual gRPC methods.
The library will automatically use the defaults defined in DatabaseAdminStubSettings if no custom settings are set. The defaults are the same as the defaults that are used by DatabaseAdminSettings, and are generated from the file spanner_admin_database_gapic.yaml. Retries are configured for idempotent methods but not for non-idempotent methods.
You can set the same RetrySettings for all unary methods by calling this:
builder
.getDatabaseAdminStubSettingsBuilder()
.applyToAllUnaryMethods(
new ApiFunction<UnaryCallSettings.Builder<?, ?>, Void>() {
public Void apply(Builder<?, ?> input) {
input.setRetrySettings(retrySettings);
return null;
}
});
| Type | Description |
| DatabaseAdminStubSettings.Builder |
getInstanceAdminStubSettingsBuilder()
public InstanceAdminStubSettings.Builder getInstanceAdminStubSettingsBuilder()Returns the InstanceAdminStubSettings.Builder that will be used to build the SpannerRpc. Use this to set custom RetrySettings for individual gRPC methods.
The library will automatically use the defaults defined in InstanceAdminStubSettings if no custom settings are set. The defaults are the same as the defaults that are used by InstanceAdminSettings, and are generated from the file spanner_admin_instance_gapic.yaml. Retries are configured for idempotent methods but not for non-idempotent methods.
You can set the same RetrySettings for all unary methods by calling this:
builder
.getInstanceAdminStubSettingsBuilder()
.applyToAllUnaryMethods(
new ApiFunction<UnaryCallSettings.Builder<?, ?>, Void>() {
public Void apply(Builder<?, ?> input) {
input.setRetrySettings(retrySettings);
return null;
}
});

setAsyncExecutorProvider(SpannerOptions.CloseableExecutorProvider provider)
public SpannerOptions.Builder setAsyncExecutorProvider(SpannerOptions.CloseableExecutorProvider provider)Sets the ExecutorProvider to use for high-level async calls that need an executor, such as fetching results for an AsyncResultSet.
Async methods will use a sensible default if no custom ExecutorProvider has been set. The default ExecutorProvider uses a cached thread pool containing a maximum of 8 threads. The pool is lazily initialized and will not create any threads if the user application does not use any async methods. It will also scale down the thread usage if the async load allows for that.
Call SpannerOptions#createAsyncExecutorProvider(int, long, TimeUnit) to create a provider with a custom pool size or call FixedCloseableExecutorProvider#create(ScheduledExecutorService) to create a CloseableExecutorProvider from a standard Java ScheduledExecutorService.
| Name | Description |
| provider | SpannerOptions.CloseableExecutorProvider |
| Type | Description |
| SpannerOptions.Builder |
setAutoThrottleAdministrativeRequests()
public SpannerOptions.Builder setAutoThrottleAdministrativeRequests()Instructs the client library to automatically throttle the number of administrative requests if the rate of administrative requests generated by this Spanner instance will exceed the administrative limits Cloud Spanner. The default behavior is to not throttle any requests. If the limit is exceeded, Cloud Spanner will return a RESOURCE_EXHAUSTED error. More information on the administrative limits can be found here: https://cloud.google.com/spanner/quotas#administrative_limits. Setting this option is not a guarantee that the rate will never be exceeded, as this option will only throttle requests coming from this client. Additional requests from other clients could still cause the limit to be exceeded.
| Type | Description |
| SpannerOptions.Builder |
setCallCredentialsProvider(SpannerOptions.CallCredentialsProvider callCredentialsProvider)
public SpannerOptions.Builder setCallCredentialsProvider(SpannerOptions.CallCredentialsProvider callCredentialsProvider)Sets a CallCredentialsProvider that can deliver CallCredentials to use on a per-gRPC basis. Any credentials returned by this CallCredentialsProvider will have preference above any Credentials that may have been set on the SpannerOptions instance.
| Name | Description |
| callCredentialsProvider | SpannerOptions.CallCredentialsProvider |
| Type | Description |

setChannelConfigurator(ApiFunction<ManagedChannelBuilder,ManagedChannelBuilder> channelConfigurator)
public SpannerOptions.Builder setChannelConfigurator(ApiFunction<ManagedChannelBuilder,ManagedChannelBuilder> channelConfigurator)Sets an ApiFunction that will be used to configure the transport channel. This will only be used if no custom TransportChannelProvider has been set.
| Name | Description |
| channelConfigurator | ApiFunction<io.grpc.ManagedChannelBuilder,io.grpc.ManagedChannelBuilder> |
| Type | Description |
| SpannerOptions.Builder |
setChannelProvider(TransportChannelProvider channelProvider)
public SpannerOptions.Builder setChannelProvider(TransportChannelProvider channelProvider)Sets the ChannelProvider. GapicSpannerRpc would create a default one if none
is provided.
Setting a custom TransportChannelProvider also overrides any other settings that affect the default channel provider. These must be set manually on the custom TransportChannelProvider instead of on SpannerOptions. The settings of SpannerOptions that have no effect if you set a custom TransportChannelProvider are:
- #setChannelConfigurator(ApiFunction)
- #setHost(String)
- #setNumChannels(int)
- #setInterceptorProvider(GrpcInterceptorProvider)
- #setHeaderProvider(com.google.api.gax.rpc.HeaderProvider)
| Name | Description |
| channelProvider | TransportChannelProvider |
| Type | Description |
| SpannerOptions.Builder |
setCompressorName(String compressorName)
public SpannerOptions.Builder setCompressorName(String compressorName)Sets the compression to use for all gRPC calls. The compressor must be a valid name known in the CompressorRegistry.
Supported values are:
- gzip: Enable gzip compression
- identity: Disable compression
null: Use default compression
| Name | Description |
| compressorName | String |
| Type | Description |
| SpannerOptions.Builder |
setDefaultQueryOptions(DatabaseId database, ExecuteSqlRequest.QueryOptions defaultQueryOptions)
public SpannerOptions.Builder setDefaultQueryOptions(DatabaseId database, ExecuteSqlRequest.QueryOptions defaultQueryOptions)Sets the default QueryOptions that will be used for all queries on the specified database. Query options can also be specified on a per-query basis and as environment variables. The precedence of these settings are:
- Query options for a specific query
- Environment variables
- These default query options
Each QueryOption value that is used for a query is determined individually based on the above precedence. If for example a value for QueryOptions#getOptimizerVersion() is specified in an environment variable and a value for QueryOptions#getOptimizerStatisticsPackage() is specified for a specific query, both values will be used for the specific query. Environment variables are only read during the initialization of a SpannerOptions instance. Changing an environment variable after initializing a SpannerOptions instance will not have any effect on that instance.
| Name | Description |
| database | DatabaseId |
| defaultQueryOptions | ExecuteSqlRequest.QueryOptions |
| Type | Description |
| SpannerOptions.Builder |
setEmulatorHost(String emulatorHost)
public SpannerOptions.Builder setEmulatorHost(String emulatorHost)Sets the host of an emulator to use. By default the value is read from an environment
variable. If the environment variable is not set, this will be null.
| Name | Description |
| emulatorHost | String |
| Type | Description |
| SpannerOptions.Builder |
setHost(String host)
public SpannerOptions.Builder setHost(String host)| Name | Description |
| host | String |

setPartitionedDmlTimeout(Duration timeout)
public SpannerOptions.Builder setPartitionedDmlTimeout(Duration timeout)Sets a timeout specifically for Partitioned DML statements executed through DatabaseClient#executePartitionedUpdate(Statement). The default is 2 hours.
| Name | Description |
| timeout | org.threeten.bp.Duration |
| Type | Description |
| SpannerOptions.Builder |
setPrefetchChunks(int prefetchChunks)
public SpannerOptions.Builder setPrefetchChunks(int prefetchChunks)Specifying this will allow the client to prefetch up to prefetchChunks
PartialResultSet chunks for each read and query. The data size of each chunk depends on the
server implementation but a good rule of thumb is that each chunk will be up to 1 MiB. Larger
values reduce the likelihood of blocking while consuming results at the cost of greater
memory consumption. prefetchChunks should be greater than 0. To get good performance
choose a value that is large enough to allow buffering of chunks for an entire row. Apart
from the buffered chunks, there can be at most one more row buffered in the client. This can
be overridden on a per read/query basis by Options#prefetchChunks(). If unspecified,
we will use a default value (currently 4).
| Name | Description |
| prefetchChunks | int |
| Type | Description |
| SpannerOptions.Builder |
setRetrySettings(RetrySettings retrySettings)
public SpannerOptions.Builder setRetrySettings(RetrySettings retrySettings)SpannerOptions.Builder does not support global retry settings, as it creates three different gRPC clients: Spanner, DatabaseAdminClient and InstanceAdminClient. Instead of calling this method, you should set specific RetrySettings for each of the underlying gRPC clients by calling respectively #getSpannerStubSettingsBuilder(), #getDatabaseAdminStubSettingsBuilder() or #getInstanceAdminStubSettingsBuilder().
| Name | Description |
| retrySettings | RetrySettings |

| Name | Description |
| sessionLabels | Map<String,String>Map from label key to label value. Label key and value cannot be null. For more information on valid syntax see api docs . |
| Type | Description |
| SpannerOptions.Builder |
setSessionPoolOption(SessionPoolOptions sessionPoolOptions)
public SpannerOptions.Builder setSessionPoolOption(SessionPoolOptions sessionPoolOptions)Sets the options for managing the session pool. If not specified then the default
SessionPoolOptions is used.

setTrackTransactionStarter()
public SpannerOptions.Builder setTrackTransactionStarter()Instructs the client library to track the first request of each read/write transaction. This statement will include a BeginTransaction option and will return a transaction id as part of its result. All other statements in the same transaction must wait for this first statement to finish before they can proceed. By setting this option the client library will throw a SpannerException with ErrorCode#DEADLINE_EXCEEDED for any subsequent statement that has waited for at least 60 seconds for the first statement to return a transaction id, including the stacktrace of the initial statement that should have returned a transaction id.
