Functions

func TrimLeadingWhitespace 

func TrimLeadingWhitespace(commandStr string) (newCommand string)

TrimLeadingWhitespace removes leading whitespace, so that Python code blocks that are embedded into Go code still could be interpreted properly.

Types

type CancelCommand 

type CancelCommand struct {
	ClusterId string `json:"clusterId,omitempty"`

	CommandId string `json:"commandId,omitempty"`

	ContextId string `json:"contextId,omitempty"`
}

type Command 

type Command struct {
	// Running cluster id
	ClusterId string `json:"clusterId,omitempty"`
	// Executable code
	Command string `json:"command,omitempty"`
	// Running context id
	ContextId string `json:"contextId,omitempty"`

	Language Language `json:"language,omitempty"`
}

type CommandExecutionAPI 

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

This API allows execution of Python, Scala, SQL, or R commands on running Databricks Clusters.

func NewCommandExecution 

func NewCommandExecution(client *client.DatabricksClient) *CommandExecutionAPI

func (*CommandExecutionAPI) Cancel 

func (a *CommandExecutionAPI) Cancel(ctx context.Context, request CancelCommand) error

Cancel a command.

Cancels a currently running command within an execution context.

The command ID is obtained from a prior successful call to __execute__.

func (*CommandExecutionAPI) CancelAndWait 

func (a *CommandExecutionAPI) CancelAndWait(ctx context.Context, cancelCommand CancelCommand, options ...retries.Option[CommandStatusResponse]) (*CommandStatusResponse, error)

Calls CommandExecutionAPI.Cancel and waits to reach Cancelled state

You can override the default timeout of 20 minutes by calling adding retries.Timeout[CommandStatusResponse](60*time.Minute) functional option.

func (*CommandExecutionAPI) CommandStatus 

func (a *CommandExecutionAPI) CommandStatus(ctx context.Context, request CommandStatusRequest) (*CommandStatusResponse, error)

Get command info.

Gets the status of and, if available, the results from a currently executing command.

The command ID is obtained from a prior successful call to __execute__.

Creates an execution context for running cluster commands.

If successful, this method returns the ID of the new execution context.

func (*CommandExecutionAPI) CreateAndWait 

func (a *CommandExecutionAPI) CreateAndWait(ctx context.Context, createContext CreateContext, options ...retries.Option[ContextStatusResponse]) (*ContextStatusResponse, error)

Runs a cluster command in the given execution context, using the provided language.

If successful, it returns an ID for tracking the status of the command's execution.

func (*CommandExecutionAPI) ExecuteAndWait 

func (a *CommandExecutionAPI) ExecuteAndWait(ctx context.Context, command Command, options ...retries.Option[CommandStatusResponse]) (*CommandStatusResponse, error)
