sdk-backend-spi package

This package provides definitions of the Service Provider Interface (SPI) for the Analytical Backend.

Remarks

The interface defines functionality to be implemented for a particular backend to be used in GoodData.UI. The Analytical Backend SPI for GoodData Cloud and GoodData.CN (joint codename tiger in @gooddata/sdk-backend-tiger) is almost fully implemented.

Classes

Class	Description
AbortError	This exception is thrown when the request is canceled.
ContractExpired	This exception is thrown when a contract has expired, for example if a plan's trial period has ended
DataTooLargeError	This exception MUST be thrown when backend execution identifies that there is too much data to process for the execution and refuses to proceed.
LimitReached	This exception is thrown when the limit of objects that can be created on backend is reached, for example if no more workspaces can be created because of the plan limits.
NoDataError	This exception MUST be thrown when the backend execution identifies that there is no data to calculate.
NotAuthenticated	This exception is thrown when client code triggers an operation which requires authentication but the client code did not provide credentials or the credentials are invalid.
NotImplemented	This exception is thrown when client code asks Analytical Backend to exercise a feature that is not implemented yet.
NotSupported	This exception is thrown when client code asks Analytical Backend to exercise an unsupported feature.
ProtectedDataError	This exception MUST be thrown when backend execution identifies that the data to calculate results for is protected and the caller lacks the sufficient authorization.
TimeoutError	This error means that during a repeated polling for some resource, we did not reach 200 response within the certain number of attempts/time.
UnexpectedError	This exception MUST be thrown when the unexpected happens. This is a last-resort error type that SHOULD be used if the erroneous state cannot be categorized in a better way.
UnexpectedResponseError	This exception MUST be thrown when communication with the backend encounters an unexpected response status code and it cannot handle or categorize it to a known, domain-specific error.
