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`	`CheckAndMutateRowRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task<CheckAndMutateRowResponse>`	The response to send back to the client (wrapped by a task).

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`	`MutateRowRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task<MutateRowResponse>`	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`	`MutateRowsRequest` The request received from the client.
`responseStream`	`IServerStreamWriter<MutateRowsResponse>` Used for sending responses back to the client.
`context`	`ServerCallContext` The 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`	`ReadModifyWriteRowRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task<ReadModifyWriteRowResponse>`	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`	`ReadRowsRequest` The request received from the client.
`responseStream`	`IServerStreamWriter<ReadRowsResponse>` Used for sending responses back to the client.
`context`	`ServerCallContext` The 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`	`SampleRowKeysRequest` The request received from the client.
`responseStream`	`IServerStreamWriter<SampleRowKeysResponse>` Used for sending responses back to the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task`	A task indicating completion of the handler.
