Types

type Config

type Config struct {
	// Type defines the type of storage backend, e.g. "etcd2", etcd3". Default ("") is "etcd3".
	Type string
	// Prefix is the prefix to all keys passed to storage.Interface methods.
	Prefix string
	// ServerList is the list of storage servers to connect with.
	ServerList []string
	// TLS credentials
	KeyFile  string
	CertFile string
	CAFile   string
	// Quorum indicates that whether read operations should be quorum-level consistent.
	Quorum bool
	// Paging indicates whether the server implementation should allow paging (if it is
	// supported). This is generally configured by feature gating, or by a specific
	// resource type not wishing to allow paging, and is not intended for end users to
	// set.
	Paging bool
	// DeserializationCacheSize is the size of cache of deserialized objects.
	// Currently this is only supported in etcd2.
	// We will drop the cache once using protobuf.
	DeserializationCacheSize int

	Codec runtime.Codec
	// Transformer allows the value to be transformed prior to persisting into etcd.
	Transformer value.Transformer

	// CompactionInterval is an interval of requesting compaction from apiserver.
	// If the value is 0, no compaction will be issued.
	CompactionInterval time.Duration

	// CountMetricPollPeriod specifies how often should count metric be updated
	CountMetricPollPeriod time.Duration
}

Config is configuration for creating a storage backend.
