class google.cloud.pubsublite_v1.Cursor(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A cursor that describes the position of a message within a topic partition.

offset()

The offset of a message within a topic partition. Must be greater than or equal 0.

class google.cloud.pubsublite_v1.Subscription(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Metadata about a subscription resource.

name()

The name of the subscription. Structured like: projects/{project_number}/locations/{location}/subscriptions/{subscription_id}

topic()

The name of the topic this subscription is attached to. Structured like: projects/{project_number}/locations/{location}/topics/{topic_id}

delivery_config()

The settings for this subscription’s message delivery.

  • Type

    google.cloud.pubsublite_v1.types.Subscription.DeliveryConfig

export_config()

If present, messages are automatically written from the Pub/Sub Lite topic associated with this subscription to a destination.

  • Type

    google.cloud.pubsublite_v1.types.ExportConfig

class DeliveryConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The settings for a subscription’s message delivery.

delivery_requirement()

The DeliveryRequirement for this subscription.

  • Type

    google.cloud.pubsublite_v1.types.Subscription.DeliveryConfig.DeliveryRequirement

class DeliveryRequirement(value)

When this subscription should send messages to subscribers relative to messages persistence in storage. For details, see Creating Lite subscriptions.

Values:

DELIVERY_REQUIREMENT_UNSPECIFIED (0):

    Default value. This value is unused.

DELIVER_IMMEDIATELY (1):

    The server does not wait for a published
    message to be successfully written to storage
    before delivering it to subscribers.

DELIVER_AFTER_STORED (2):

    The server will not deliver a published
    message to subscribers until the message has
    been successfully written to storage. This will
    result in higher end-to-end latency, but
    consistent delivery.

class google.cloud.pubsublite_v1.Topic(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Metadata about a topic resource.

name()

The name of the topic. Structured like: projects/{project_number}/locations/{location}/topics/{topic_id}

partition_config()

The settings for this topic’s partitions.

  • Type

    google.cloud.pubsublite_v1.types.Topic.PartitionConfig

retention_config()

The settings for this topic’s message retention.

  • Type

    google.cloud.pubsublite_v1.types.Topic.RetentionConfig

reservation_config()

The settings for this topic’s Reservation usage.

  • Type

    google.cloud.pubsublite_v1.types.Topic.ReservationConfig

class PartitionConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The settings for a topic’s partitions.

This message has oneof fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.

count()

The number of partitions in the topic. Must be at least 1.

Once a topic has been created the number of partitions can be increased but not decreased. Message ordering is not guaranteed across a topic resize. For more information see https://cloud.google.com/pubsub/lite/docs/topics#scaling_capacity

scale()

DEPRECATED: Use capacity instead which can express a superset of configurations.

Every partition in the topic is allocated throughput equivalent to scale times the standard partition throughput (4 MiB/s). This is also reflected in the cost of this topic; a topic with scale of 2 and count of 10 is charged for 20 partitions. This value must be in the range [1,4].

This field is a member of oneof dimension.

capacity()

The capacity configuration.

This field is a member of oneof dimension.

  • Type

    google.cloud.pubsublite_v1.types.Topic.PartitionConfig.Capacity

class Capacity(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The throughput capacity configuration for each partition.

publish_mib_per_sec()

Publish throughput capacity per partition in MiB/s. Must be >= 4 and <= 16.

subscribe_mib_per_sec()

Subscribe throughput capacity per partition in MiB/s. Must be >= 4 and <= 32.

class ReservationConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The settings for this topic’s Reservation usage.

throughput_reservation()

The Reservation to use for this topic’s throughput capacity. Structured like: projects/{project_number}/locations/{location}/reservations/{reservation_id}

class RetentionConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The settings for a topic’s message retention.

per_partition_bytes()

The provisioned storage, in bytes, per partition. If the number of bytes stored in any of the topic’s partitions grows beyond this value, older messages will be dropped to make room for newer ones, regardless of the value of period.

period()

How long a published message is retained. If unset, messages will be retained as long as the bytes retained for each partition is below per_partition_bytes.
