}

func NewPaginationStore 

func NewPaginationStore(delegate ResourceStore) ResourceStore

The Pagination Store is handling only the pagination functionality in the List. This is an in-memory operation and offloads this from the persistent stores (k8s, postgres etc.) Two reasons why this is needed: * There is no filtering + pagination on the native K8S database * On Postgres, we keep the object in a column as a string. We would have to use JSON column type and convert it to native SQL queries.

The in-memory filtering has been tested with 10,000 Dataplanes and proved to be fast enough, although not that efficient.

type ResourceStoreWrapper 

type ResourceStoreWrapper = func(delegate ResourceStore) ResourceStore

ResourceStoreWrapper is a function that takes a ResourceStore and returns a wrapped ResourceStore. The wrapped ResourceStore can be used to modify or augment the behavior of the original ResourceStore.

type Transaction 

type Transaction interface {
	Commit(ctx context.Context) error
	Rollback(ctx context.Context) error
}

func TxFromCtx 

func TxFromCtx(ctx context.Context) (Transaction, bool)

type Transactions 

type Transactions interface {
	Begin(ctx context.Context) (Transaction, error)
}

Transactions is a producer of transactions if a resource store support transactions. Transactions are never required for consistency in dubbo, because there are ResourceStores that does not support transactions. However, in a couple of cases executing queries in transaction can improve the performance.

In case of Postgres, you may set hooks when retrieve and release connections for the connection pool. In this case, if you create multiple resources, you need to acquire connection and execute hooks for each create. If you create transaction for it, you execute hooks once and you hold the connection.

Transaction is propagated implicitly through Context.

type UpdateOptions 

type UpdateOptions struct {
	Name             string
	Mesh             string
	ModificationTime time.Time
