transactions to the leader region.
getAllowedClientLibTokens()
protected Set<String> getAllowedClientLibTokens()
Overrides
com.google.cloud.ServiceOptions.Builder.getAllowedClientLibTokens()
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;
}
});
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;
}
});
getSpannerStubSettingsBuilder()
public SpannerStubSettings.Builder getSpannerStubSettingsBuilder()
Returns the SpannerStubSettings.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 SpannerStubSettings if
no custom settings are set. The defaults are the same as the defaults that are used by SpannerSettings, and are generated from the file spanner_gapic.yaml.
Retries are configured for idempotent methods but not for non-idempotent methods.

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.
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.
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.
setChannelConfigurator(ApiFunction<ManagedChannelBuilder,ManagedChannelBuilder> channelConfigurator)
public SpannerOptions.Builder setChannelConfigurator(ApiFunction<ManagedChannelBuilder,ManagedChannelBuilder> channelConfigurator)
| Parameter |
|---|
| Name | Description |
channelConfigurator | ApiFunction<io.grpc.ManagedChannelBuilder,io.grpc.ManagedChannelBuilder>
|
setChannelProvider(TransportChannelProvider channelProvider)
public SpannerOptions.Builder setChannelProvider(TransportChannelProvider channelProvider)
setClientLibToken(String clientLibToken)
public SpannerOptions.Builder setClientLibToken(String clientLibToken)
| Parameter |
|---|
| Name | Description |
clientLibToken | String
|
Overrides
com.google.cloud.ServiceOptions.Builder.setClientLibToken(java.lang.String)
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. This will enable compression both from the client to the
server and from the server to the client.
Supported values are:
- gzip: Enable gzip compression
- identity: Disable compression
null: Use default compression
| Parameter |
|---|
| Name | Description |
compressorName | String
|
setDatabaseRole(String databaseRole)
public SpannerOptions.Builder setDatabaseRole(String databaseRole)
Sets the database role that should be used for connections that are created by this instance.
The database role that is used determines the access permissions that a connection has. This
can for example be used to create connections that are only permitted to access certain
tables.
| Parameter |
|---|
| Name | Description |
databaseRole | String
|
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.
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.
| Parameter |
|---|
| Name | Description |
emulatorHost | String
|
setHost(String host)
public SpannerOptions.Builder setHost(String host)
| Parameter |
|---|
| Name | Description |
host | String
|
Overrides
com.google.cloud.ServiceOptions.Builder.setHost(java.lang.String)
setInterceptorProvider(GrpcInterceptorProvider interceptorProvider)
public SpannerOptions.Builder setInterceptorProvider(GrpcInterceptorProvider interceptorProvider)
Sets the GrpcInterceptorProvider. GapicSpannerRpc would create a default one
if none is provided.
setNumChannels(int numChannels)
public SpannerOptions.Builder setNumChannels(int numChannels)
Sets the number of gRPC channels to use. By default 4 channels are created per SpannerOptions.
| Parameter |
|---|
| Name | Description |
numChannels | int
|
setPartitionedDmlTimeout(Duration timeout)
public SpannerOptions.Builder setPartitionedDmlTimeout(Duration timeout)
| Parameter |
|---|
| Name | Description |
timeout | org.threeten.bp.Duration
|
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).
| Parameter |
|---|
| Name | Description |
prefetchChunks | int
|
setRetrySettings(RetrySettings retrySettings)
public SpannerOptions.Builder setRetrySettings(RetrySettings retrySettings)
Overrides
com.google.cloud.ServiceOptions.Builder.setRetrySettings(com.google.api.gax.retrying.RetrySettings)
setSessionLabels(Map<String,String> sessionLabels)
public SpannerOptions.Builder setSessionLabels(Map<String,String> sessionLabels)
Sets the labels to add to all Sessions created in this client.
| Parameter |
|---|
| 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 .

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.
setTransportOptions(TransportOptions transportOptions)
public SpannerOptions.Builder setTransportOptions(TransportOptions transportOptions)
| Parameter |
|---|
| Name | Description |
transportOptions | com.google.cloud.TransportOptions
