Functions ¶

func BucketExists ¶

func BucketExists(ctx context.Context, store ObjectStore, bucket string) bool

BucketExists reports whether bucket is present in store.

func Encode ¶

func Encode(t *Table, format, compression, baseName string) ([]byte, string, error)

Encode renders t as format with compression and returns the body and the file extension. Parquet is always internally compressed (snappy) and ignores compression.

func ProductCode ¶

func ProductCode(service string) string

ProductCode maps a Cost Explorer service name to its billing product code.

func Put ¶

func Put(ctx context.Context, store ObjectStore, bucket, key string, body []byte, contentType string) error

Put writes body to bucket/key.

func SnakeCase ¶

func SnakeCase(s string) string

SnakeCase converts "lineItem/UsageAccountId" style names to "line_item_usage_account_id".

Types ¶

type Column ¶

type Column struct {
	Name string
	Type string
}

Column is one output column.

type CostLine ¶

type CostLine struct {
	Day       time.Time
	Service   string
	Region    string
	UsageType string
	Account   string
	Blended   float64
	Unblended float64
	Usage     float64
}

CostLine is one day of cost for a service/region/usage-type/account combination.

type CostSource ¶

type CostSource interface {
	CostLines(start, end time.Time) []CostLine
}

CostSource yields the daily cost lines with start <= Day < end.

type ObjectStore ¶

type ObjectStore interface {
	PutObject(ctx context.Context, in *sdk_s3.PutObjectInput) (*sdk_s3.PutObjectOutput, error)
	HeadBucket(ctx context.Context, in *sdk_s3.HeadBucketInput) (*sdk_s3.HeadBucketOutput, error)
}

ObjectStore is the S3 surface report delivery writes to.

type Table ¶

type Table struct {
	Columns []Column
	Rows    [][]any
}

Table is a header plus rows; a cell is a string, float64 or nil.
