Functions

func BuildIteratorPools

func BuildIteratorPools() encoding.IteratorPools

BuildIteratorPools build iterator pools if they are unavailable from m3db (e.g. if running standalone query)

func BuildWorkerPools

func BuildWorkerPools(
	cfg config.Configuration,
	logger *zap.Logger,
	scope tally.Scope,
) (pool.ObjectPool, instrument.Options)

BuildWorkerPools builds a worker pool

Types

type PoolWrapper

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

PoolWrapper is an asynchronous wrapper for iterator pools

func NewAsyncPoolsWrapper

func NewAsyncPoolsWrapper() *PoolWrapper

NewAsyncPoolsWrapper creates a pool wrapper which must be initialized

func NewPoolsWrapper

func NewPoolsWrapper(pools encoding.IteratorPools) *PoolWrapper

NewPoolsWrapper creates an initialized pool wrapper

func (*PoolWrapper) Init

func (w *PoolWrapper) Init(
	sessionPools encoding.IteratorPools,
	err error,
)

Init initializes the wrapper with iterator pools and notifies any watchers

func (*PoolWrapper) IteratorPools

func (w *PoolWrapper) IteratorPools() (
	bool, encoding.IteratorPools, error, <-chan encoding.IteratorPools, <-chan error)

nolint IteratorPools either returns iterator pools and errors, or channels that will be notified when iterator pools become available
