	ColumnName string // column_name
	Storing    bool   // storing column or not
}

SpannerIndexColumn represents index column info.

type SpannerTable

type SpannerTable struct {
	TableName       string // table_name
	ParentTableName string
}

SpannerTable represents table info.

type TypeLoader

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

TypeLoader provides a common Loader implementation used by the built in schema/query loaders.
