Overview ¶
Package storage is the collection of different storage interfaces that are shared by two or more components.
If a storage is used by only one component, its interface should be defined in the component package, and implementations under ./plugin/storage/{db_name}/{store_type}/....

Variables ¶
var (
// ErrArchiveStorageNotConfigured can be returned by the ArchiveFactory when the archive storage is not configured.
ErrArchiveStorageNotConfigured = errors.New("Archive storage not configured")
// ErrArchiveStorageNotSupported can be returned by the ArchiveFactory when the archive storage is not supported by the backend.
ErrArchiveStorageNotSupported = errors.New("Archive storage not supported")
)

Types ¶
type ArchiveFactory ¶
type ArchiveFactory interface {
// CreateArchiveSpanReader creates a spanstore.Reader.
CreateArchiveSpanReader() (spanstore.Reader, error)
// CreateArchiveSpanWriter creates a spanstore.Writer.
CreateArchiveSpanWriter() (spanstore.Writer, error)
}
ArchiveFactory is an additional interface that can be implemented by a factory to support trace archiving.
type Factory ¶
type Factory interface {
// Initialize performs internal initialization of the factory, such as opening connections to the backend store.
// It is called after all configuration of the factory itself has been done.
Initialize(metricsFactory metrics.Factory, logger *zap.Logger) error
// CreateSpanReader creates a spanstore.Reader.
CreateSpanReader() (spanstore.Reader, error)
// CreateSpanWriter creates a spanstore.Writer.
CreateSpanWriter() (spanstore.Writer, error)
// CreateDependencyReader creates a dependencystore.Reader.
CreateDependencyReader() (dependencystore.Reader, error)
}
Factory defines an interface for a factory that can create implementations of different storage components. Implementations are also encouraged to implement plugin.Configurable interface.
