func (c *AcceptedValuesCheck) Check(ctx context.Context, ti *scheduler.ColumnCheckInstance) error

type AssetMaterializationMap

type AssetMaterializationMap map[pipeline.MaterializationType]map[pipeline.MaterializationStrategy]MaterializerFunc

type BasicOperator

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

func NewBasicOperator

func NewBasicOperator(conn connectionFetcher, extractor queryExtractor, materializer materializer) *BasicOperator

func (BasicOperator) Run

func (o BasicOperator) Run(ctx context.Context, ti scheduler.TaskInstance) error

func (BasicOperator) RunTask

type Client

type Client interface {
	RunQueryWithoutResult(ctx context.Context, query *query.Query) error
	Select(ctx context.Context, query *query.Query) ([][]interface{}, error)
}

type Config

type Config struct {
	// Token is the Databricks Personal API token
	Token string
	Host  string
	Port  int
	// Path will determine cluster or sql warehouse. See https://docs.databricks.com/en/dev-tools/go-sql-driver.html#connect-with-a-dsn-connection-string
	Path    string
	Catalog string
	Schema  string
}

func (*Config) ToDBConnectionURI

func (c *Config) ToDBConnectionURI() string

type DB

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

func NewDB

func NewDB(c *Config) (*DB, error)

func (*DB) RunQueryWithoutResult

func (db *DB) RunQueryWithoutResult(ctx context.Context, query *query.Query) error

func (*DB) Select

type Materializer

type Materializer struct {
	MaterializationMap AssetMaterializationMap
	// contains filtered or unexported fields
}

The other packages all use a materializer that renders the query to a single string. Due to the quirks of databricks we need to create a different materializer that returns a slice of strings, since databricks server requires us to send separate batches for certain things.
