Overview 

NOTE: This package is in alpha. It is not stable, and is likely to change.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type CallOptions 

type CallOptions struct {
	GetTable        []gax.CallOption
	ListTables      []gax.CallOption
	GetRow          []gax.CallOption
	ListRows        []gax.CallOption
	CreateRow       []gax.CallOption
	BatchCreateRows []gax.CallOption
	UpdateRow       []gax.CallOption
	BatchUpdateRows []gax.CallOption
	DeleteRow       []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with .

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new tables service client.

The Tables Service provides an API for reading and updating tables. It defines the following resource model: 

The API has a collection of [Table][google.area120.tables.v1alpha1.Table]
resources, named tables/*

Each Table has a collection of [Row][google.area120.tables.v1alpha1.Row]
resources, named tables/*/rows/*
Example 
package main

import (
	"context"

	tables "cloud.google.com/go/area120/tables/apiv1alpha1"
)

func main() {
	ctx := context.Background()
	c, err := tables.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use client.
	_ = c
}

Output:

func (*Client) BatchCreateRows 

func (c *Client) BatchCreateRows(ctx context.Context, req *tablespb.BatchCreateRowsRequest, opts ...gax.CallOption) (*tablespb.BatchCreateRowsResponse, error)

BatchCreateRows creates multiple rows.
