Types

type Bootstrapper

type Bootstrapper interface {
	// String returns the name of the bootstrapper
	String() string

	// Bootstrap performs bootstrapping of series data and index metadata
	// for the  given time ranges, returning the bootstrapped series data
	// and index blocks for the time ranges it's unable to fulfill in parallel.
	// A bootstrapper should only return an error should it want to entirely
	// cancel the bootstrapping of the node, i.e. non-recoverable situation
	// like not being able to read from the filesystem.
	Bootstrap(ctx context.Context, namespaces Namespaces, cache Cache) (NamespaceResults, error)
}

Bootstrapper is the interface for different bootstrapping mechanisms. Note that a bootstrapper can and will be reused so it is important to not rely on state stored in the bootstrapper itself with the mindset that it will always be set to default values from the constructor.

type BootstrapperProvider

type BootstrapperProvider interface {
	// String returns the name of the bootstrapper.
	String() string

	// Provide constructs a bootstrapper.
	Provide() (Bootstrapper, error)
}

BootstrapperProvider constructs a bootstrapper.

type Cache added in v0.15.16

type Cache interface {
	// InfoFilesForNamespace returns the info files grouped by namespace.
	InfoFilesForNamespace(ns namespace.Metadata) (InfoFileResultsPerShard, error)

	// InfoFilesForShard returns the info files grouped by shard for the provided namespace.
	InfoFilesForShard(ns namespace.Metadata, shard uint32) ([]fs.ReadInfoFileResult, error)

	// ReadInfoFiles returns info file results for each shard grouped by namespace. A cached copy
	// is returned if the info files have already been read.
	ReadInfoFiles() InfoFilesByNamespace

	// Evict cache contents by re-reading fresh data in.
	Evict()
}

Cache provides a snapshot of info files for use throughout all stages of the bootstrap.

func NewCache added in v0.15.16

func NewCache(options CacheOptions) (Cache, error)

NewCache creates a cache specifically to be used during the bootstrap process. Primarily a mechanism for passing info files along without needing to re-read them at each stage of the bootstrap process.

type CacheOptions added in v0.15.16

type CacheOptions interface {
	// Validate will validate the options and return an error if not valid.
	Validate() error

	// SetFilesystemOptions sets the filesystem options.
	SetFilesystemOptions(value fs.Options) CacheOptions

	// FilesystemOptions returns the filesystem options.
	FilesystemOptions() fs.Options

	// SetNamespaceDetails sets the namespaces to cache information for.
	SetNamespaceDetails(value []NamespaceDetails) CacheOptions

	// NamespaceDetails returns the namespaces to cache information for.
	NamespaceDetails() []NamespaceDetails

	// SetInstrumentOptions sets the instrument options.
	SetInstrumentOptions(value instrument.Options) CacheOptions

	// InstrumentOptions returns the instrument options.
	InstrumentOptions() instrument.Options
}

CacheOptions represents the options for Cache.
