Methods

build()

public BigtableDataSettings build()

Returns
Type	Description
`BigtableDataSettings`

disableBatchMutationLatencyBasedThrottling()

public BigtableDataSettings.Builder disableBatchMutationLatencyBasedThrottling()

Disable latency based throttling for BigtableDataClient#newBulkMutationBatcher(String).

Returns
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.

Parameter
Name	Description
`targetRpcLatencyMs`	`long`

Returns
Type	Description
`BigtableDataSettings.Builder`

getAppProfileId()

public String getAppProfileId()

Gets the app profile id that was previously set on this Builder.

Returns
Type	Description
`String`

getCredentialsProvider()

public CredentialsProvider getCredentialsProvider()

Gets the CredentialsProvider to use for getting the credentials to make calls with.

Returns
Type	Description
`CredentialsProvider`

getInstanceId()

public String getInstanceId()

Gets the instance id that was previously set on this Builder.

Returns
Type	Description
`String`

getPrimingTableIds() (deprecated)

public List<String> getPrimingTableIds()

Deprecated. This field is ignored. If #isRefreshingChannel() is enabled, warm up requests will be sent to all table ids of the instance.

Returns
Type	Description
`List<String>`

getProjectId()

public String getProjectId()

Gets the project id that was previously set on this Builder.

Returns
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.

Parameter
Name	Description
`credentialsProvider`	`CredentialsProvider`

Returns
Type	Description
`BigtableDataSettings.Builder`

setDefaultAppProfileId()

public BigtableDataSettings.Builder setDefaultAppProfileId()

Resets the AppProfile id to the default for the instance.

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
Name	Description
`instanceId`	`String`

Returns
Type	Description
`BigtableDataSettings.Builder`

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
Type	Description
`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.

Parameter
Name	Description
`projectId`	`String`

Returns
Type	Description
`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`

Returns
Type	Description
`BigtableDataSettings.Builder`

stubSettings()

public EnhancedBigtableStubSettings.Builder stubSettings()

Returns the underlying settings for making RPC calls. The settings should be changed with care.

Returns
Type	Description
`EnhancedBigtableStubSettings.Builder`
