consumer.go

func CreateShards Uses

func CreateShards(t require.TestingT, cmr *Consumer, specs ...*pc.ShardSpec)

CreateShards using the Consumer Apply API, and wait for them to be allocated.

func WaitForShards Uses

func WaitForShards(ctx context.Context, rjc pb.RoutedJournalClient, conn *grpc.ClientConn, sel pb.LabelSelector) error

WaitForShards queries for shards matching LabelSelector |sel|, determines the current write-heads of journals being consumed by matched shards, and polls shards until each has caught up to the determined write-heads of its consumed journals.

type Args Uses

type Args struct {
    C        require.TestingT
    Etcd     *clientv3.Client       // Etcd client instance.
    Journals pb.RoutedJournalClient // Broker client instance.
    App      consumer.Application   // Application of the consumer.
    Root     string                 // Consumer root in Etcd. Defaults to "/consumertest".
    Zone     string                 // Zone of the consumer. Defaults to "local".
    Suffix   string                 // ID Suffix of the consumer. Defaults to "consumer".
}

Args of NewConsumer.

type Consumer Uses

type Consumer struct {
    // Server is a loopback Server created for this Consumer, which is available
    // for test applications to register APIs against.
    Server *server.Server
    // Service of the Consumer, which is available for test applications.
    Service *consumer.Service
    // Tasks of the Consumer.
    Tasks *task.Group
    // contains filtered or unexported fields
}

Consumer is a lightweight, embedded Gazette consumer runtime suitable for in-process testing of consumer applications.

func NewConsumer Uses

func NewConsumer(args Args) *Consumer

NewConsumer builds and returns a Consumer.

func (*Consumer) Signal Uses

func (cmr *Consumer) Signal()

Signal the Consumer. The test Consumer will eventually exit, assuming other Consumers(s) are available to take over the assignments.

func (*Consumer) WaitForPrimary Uses

func (cmr *Consumer) WaitForPrimary(ctx context.Context, shard pc.ShardID, routeOut *pb.Route) error

WaitForPrimary of the identified shard until the Context is cancelled. If no error occurs, then the shard has a primary *Consumer (which is not necessarily this *Consumer instance). If |routeOut| is non-nil, it's populated with the current shard Route.
