disableBatchMutationLatencyBasedThrottling()
public BigtableDataSettings.Builder disableBatchMutationLatencyBasedThrottling()
Disable latency based throttling for BigtableDataClient#newBulkMutationBatcher(String).

Type | Description |
BigtableDataSettings.Builder |
enableBatchMutationLatencyBasedThrottling(long targetRpcLatencyMs)
public BigtableDataSettings.Builder enableBatchMutationLatencyBasedThrottling(long targetRpcLatencyMs)
Enable latency based throttling for BigtableDataClient#newBulkMutationBatcher(String) with a target rpc latency. The number of allowed in-flight requests will be adjusted to reach the target bulk mutations rpc latency.
The logic of adjusting in-flight request limits is as follows:
To start, Batcher allows FlowController#getCurrentElementCountLimit() in-flight elements with a total size of FlowController#getCurrentRequestBytesLimit(). Every 20 seconds, Batcher checks the mean rpc latency of the requests and compare it with the target rpc latency: if (mean latency > 3 * target latency) { decrease element count limit by 30% of FlowController#getMaxElementCountLimit() } else if (mean latency > 1.2 * target latency) { decrease element count limit by 10% of FlowController#getMaxElementCountLimit() } else if (there was throttling in the past 5 minutes && mean latency < 0.8 * target latency) { increase element count limit by 5% of FlowController#getMaxElementCountLimit() } else if (there was throttling in the past 5 minutes && parallelism is 5% of FlowController#getMaxElementCountLimit() && mean latency < 2 * target latency) { increase element count limit by 2% of FlowController#getMaxElementCountLimit() Increases are capped by FlowController#getMaxElementCountLimit(), Decreases are floored at FlowController#getMinElementCountLimit() so that there is some level of throughput.

Type | Description |
String |
getTargetRpcLatencyMsForBatchMutation()
public Long getTargetRpcLatencyMsForBatchMutation()
Gets target bulk mutation rpc latency if latency based throttling is enabled for BigtableDataClient#newBulkMutationBatcher(String). Otherwise returns null.
Returns | |
---|---|
Type | Description |
Long |
isBulkMutationFlowControlEnabled()
public boolean isBulkMutationFlowControlEnabled()
Gets if flow control is enabled for BigtableDataClient#newBulkMutationBatcher(String) based on the load of the Bigtable server.
Returns | |
---|---|
Type | Description |
boolean |
isLatencyBasedThrottlingForBatchMutationEnabled()
public boolean isLatencyBasedThrottlingForBatchMutationEnabled()
Gets if latency based throttling is enabled for BigtableDataClient#newBulkMutationBatcher(String)
Returns | |
---|---|
Type | Description |
boolean |
isRefreshingChannel() (deprecated)
public boolean isRefreshingChannel()
Deprecated. Channel refreshing is enabled by default and this method will be deprecated.
Gets if channels will gracefully refresh connections to Cloud Bigtable service.
Returns | |
---|---|
Type | Description |
boolean |
setAppProfileId(String appProfileId)
public BigtableDataSettings.Builder setAppProfileId(String appProfileId)
Sets the AppProfile to use.
An application profile (sometimes also shortened to "app profile") is a group of configuration parameters for an individual use case. A client will identify itself with an application profile ID at connection time, and the requests will be handled according to that application profile.
Parameter | |

Name | Description |
appProfileId | String |
Returns | |
---|---|
Type | Description |
BigtableDataSettings.Builder |
setBulkMutationFlowControl(boolean isEnableFlowControl)
public BigtableDataSettings.Builder setBulkMutationFlowControl(boolean isEnableFlowControl)
Configure flow control for BigtableDataClient#newBulkMutationBatcher(String) based on the current load on the Bigtable cluster.
This is different from the FlowController that's always enabled on batch reads and batch writes, which limits the number of outstanding requests to the Bigtable server.
Parameter | |

Name | Description |
isEnableFlowControl | boolean |
Returns | |
---|---|
Type | Description |
BigtableDataSettings.Builder |
setCredentialsProvider(CredentialsProvider credentialsProvider)
public BigtableDataSettings.Builder setCredentialsProvider(CredentialsProvider credentialsProvider)
Sets the CredentialsProvider to use for getting the credentials to make calls with.

credentialsProvider | CredentialsProvider |
Returns | |
---|---|
Type | Description |
BigtableDataSettings.Builder |
setDefaultAppProfileId()
public BigtableDataSettings.Builder setDefaultAppProfileId()
Resets the AppProfile id to the default for the instance.
An application profile (sometimes also shortened to "app profile") is a group of configuration parameters for an individual use case. A client will identify itself with an application profile ID at connection time, and the requests will be handled according to that application profile.
Every Bigtable Instance has a default application profile associated with it, this method configures the client to use it.
Returns | |
---|---|
Type | Description |
BigtableDataSettings.Builder |
setInstanceId(String instanceId)
public BigtableDataSettings.Builder setInstanceId(String instanceId)
Sets the target instance. This setting is required. All RPCs will be made in the context of this setting.
Parameter | |

setPrimingTableIds(String[] tableIds) (deprecated)
public BigtableDataSettings.Builder setPrimingTableIds(String[] tableIds)
Deprecated. This field is ignored. If #isRefreshingChannel() is enabled, warm up requests will be sent to all table ids of the instance.
Parameter | |
---|---|
Name | Description |
tableIds | String[] |
Returns | |
---|---|

BigtableDataSettings.Builder |
setProjectId(String projectId)
public BigtableDataSettings.Builder setProjectId(String projectId)
Sets the target project. This setting is required. All RPCs will be made in the context of this setting.

BigtableDataSettings.Builder |
setRefreshingChannel(boolean isRefreshingChannel) (deprecated)
public BigtableDataSettings.Builder setRefreshingChannel(boolean isRefreshingChannel)
Deprecated. Channel refreshing is enabled by default and this method will be deprecated.
Configure periodic gRPC channel refreshes.
This feature will gracefully refresh connections to the Cloud Bigtable service. This is a feature to address tail latency caused by the service dropping long lived gRPC connections, which causes the client to renegotiate the gRPC connection in the request path, which causes periodic spikes in latency.
Parameter | |

Name | Description |
isRefreshingChannel | boolean |

BigtableDataSettings.Builder |
stubSettings()
public EnhancedBigtableStubSettings.Builder stubSettings()
