Methods
CheckAndMutateRow(CheckAndMutateRowRequest, ServerCallContext)
public virtual Task<CheckAndMutateRowResponse> CheckAndMutateRow(CheckAndMutateRowRequest request, ServerCallContext context)Mutates a row atomically based on the output of a predicate Reader filter.
| Parameters | |
|---|---|
| Name | Description |
request | CheckAndMutateRowRequestThe request received from the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
TaskCheckAndMutateRowResponse | The response to send back to the client (wrapped by a task). |
GenerateInitialChangeStreamPartitions(GenerateInitialChangeStreamPartitionsRequest, IServerStreamWriter<GenerateInitialChangeStreamPartitionsResponse>, ServerCallContext)
public virtual Task GenerateInitialChangeStreamPartitions(GenerateInitialChangeStreamPartitionsRequest request, IServerStreamWriter<GenerateInitialChangeStreamPartitionsResponse> responseStream, ServerCallContext context)NOTE: This API is intended to be used by Apache Beam BigtableIO.
Returns the current list of partitions that make up the table's
change stream. The union of partitions will cover the entire keyspace.
Partitions can be read with ReadChangeStream.
| Parameters | |
|---|---|
| Name | Description |
request | GenerateInitialChangeStreamPartitionsRequestThe request received from the client. |
responseStream | IServerStreamWriterGenerateInitialChangeStreamPartitionsResponseUsed for sending responses back to the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
Task | A task indicating completion of the handler. |
MutateRow(MutateRowRequest, ServerCallContext)
public virtual Task<MutateRowResponse> MutateRow(MutateRowRequest request, ServerCallContext context)Mutates a row atomically. Cells already present in the row are left
unchanged unless explicitly changed by mutation.
| Parameters | |
|---|---|
| Name | Description |
request | MutateRowRequestThe request received from the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
TaskMutateRowResponse | The response to send back to the client (wrapped by a task). |
MutateRows(MutateRowsRequest, IServerStreamWriter<MutateRowsResponse>, ServerCallContext)
public virtual Task MutateRows(MutateRowsRequest request, IServerStreamWriter<MutateRowsResponse> responseStream, ServerCallContext context)Mutates multiple rows in a batch. Each individual row is mutated atomically as in MutateRow, but the entire batch is not executed atomically.
| Parameters | |
|---|---|
| Name | Description |
request | MutateRowsRequestThe request received from the client. |
responseStream | IServerStreamWriterMutateRowsResponseUsed for sending responses back to the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
Task | A task indicating completion of the handler. |
PingAndWarm(PingAndWarmRequest, ServerCallContext)
public virtual Task<PingAndWarmResponse> PingAndWarm(PingAndWarmRequest request, ServerCallContext context)Warm up associated instance metadata for this connection. This call is not required but may be useful for connection keep-alive.
| Parameters | |
|---|---|
| Name | Description |
request | PingAndWarmRequestThe request received from the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
TaskPingAndWarmResponse | The response to send back to the client (wrapped by a task). |
ReadChangeStream(ReadChangeStreamRequest, IServerStreamWriter<ReadChangeStreamResponse>, ServerCallContext)
public virtual Task ReadChangeStream(ReadChangeStreamRequest request, IServerStreamWriter<ReadChangeStreamResponse> responseStream, ServerCallContext context)NOTE: This API is intended to be used by Apache Beam BigtableIO. Reads changes from a table's change stream. Changes will reflect both user-initiated mutations and mutations that are caused by garbage collection.
| Parameters | |
|---|---|
| Name | Description |
request | ReadChangeStreamRequestThe request received from the client. |
responseStream | IServerStreamWriterReadChangeStreamResponseUsed for sending responses back to the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
Task | A task indicating completion of the handler. |
ReadModifyWriteRow(ReadModifyWriteRowRequest, ServerCallContext)
public virtual Task<ReadModifyWriteRowResponse> ReadModifyWriteRow(ReadModifyWriteRowRequest request, ServerCallContext context)Modifies a row atomically on the server. The method reads the latest existing timestamp and value from the specified columns and writes a new entry based on pre-defined read/modify/write rules. The new value for the timestamp is the greater of the existing timestamp or the current server time. The method returns the new contents of all modified cells.
| Parameters | |
|---|---|
| Name | Description |
request | ReadModifyWriteRowRequestThe request received from the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
TaskReadModifyWriteRowResponse | The response to send back to the client (wrapped by a task). |
ReadRows(ReadRowsRequest, IServerStreamWriter<ReadRowsResponse>, ServerCallContext)
public virtual Task ReadRows(ReadRowsRequest request, IServerStreamWriter<ReadRowsResponse> responseStream, ServerCallContext context)Streams back the contents of all requested rows in key order, optionally applying the same Reader filter to each. Depending on their size, rows and cells may be broken up across multiple responses, but atomicity of each row will still be preserved. See the ReadRowsResponse documentation for details.
| Parameters | |
|---|---|
| Name | Description |
request | ReadRowsRequestThe request received from the client. |
responseStream | IServerStreamWriterReadRowsResponseUsed for sending responses back to the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
Task | A task indicating completion of the handler. |
SampleRowKeys(SampleRowKeysRequest, IServerStreamWriter<SampleRowKeysResponse>, ServerCallContext)
public virtual Task SampleRowKeys(SampleRowKeysRequest request, IServerStreamWriter<SampleRowKeysResponse> responseStream, ServerCallContext context)Returns a sample of row keys in the table. The returned row keys will delimit contiguous sections of the table of approximately equal size, which can be used to break up the data for distributed tasks like mapreduces.
| Parameters | |
|---|---|
| Name | Description |
request | SampleRowKeysRequestThe request received from the client. |
responseStream | IServerStreamWriterSampleRowKeysResponseUsed for sending responses back to the client. |
context | ServerCallContextThe context of the server-side call handler being invoked. |
| Returns | |
|---|---|
| Type | Description |
Task | A task indicating completion of the handler. |
