	SchemaVersion  int64
}

Tweet is TweetTable Row

type TweetInsertReq

type TweetInsertReq struct {
	Content string `json:"content"`
}

type TweetStore

type TweetStore struct {
	// contains filtered or unexported fields
}

func NewTweetStore

func NewTweetStore(sc *spanner.Client) *TweetStore

NewTweetStore is New TweetStore

func (*TweetStore) InsertChain

func (s *TweetStore) InsertChain(ctx context.Context, content string) ([]string, error)

InsertChain is Mutation APIを利用して、複数RowのInsertを実行

func (*TweetStore) TableName

func (s *TweetStore) TableName() string

func (*TweetStore) UpdateAndSelect

func (s *TweetStore) UpdateAndSelect(ctx context.Context, id string) (int64, error)

UpdateAndSelect is Mutation APIを利用して、Updateを間に強引に挟んでみると、反映されるのかな？

func (*TweetStore) UpdateBatchDMLChain

func (s *TweetStore) UpdateBatchDMLChain(ctx context.Context, ids []string, content string) ([]string, error)

UpdateBatchDMLChain is 複数のDMLを一度に実行するtx.BatchUpdate()のサンプル
