Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

| `db` (mongoose) | `mongoose.<Model>.<operation>` (`mongoose.BlogPost.findOne`) | The operation and the collection (`findOne blogposts`), the database namespace when there is no collection, or `mongodb` when the SDK has neither |

`navigation.redirect` spans are started through the same code path as navigation spans, so they get the same names.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

| `queue.receive` | The kafkajs operation name (`poll my-topic`) | The messaging operation type and the destination (`receive my-topic`) |

| `db` (mongoose) | `mongoose.<Model>.<operation>` (`mongoose.BlogPost.findOne`) | The operation and the collection (`findOne blogposts`), the database namespace when there is no collection, or `mongodb` when the SDK has neither |

`navigation.redirect` spans are started through the same code path as navigation spans, so they get the same names.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

| `queue.process` | Integration-specific, sometimes containing per-message data (`my-queue process`, `order.created.12345 process`) | The messaging operation type and the destination (`process my-exchange`), or just the operation type when the destination has no name (`process`) |
| `queue.receive` | The kafkajs operation name (`poll my-topic`) | The messaging operation type and the destination (`receive my-topic`) |
| `cache.get`, `cache.put`, `cache.remove` | The cache key(s) (`user:123`), or for dataloader the operation and loader name (`dataloader.load usersLoader`) | The cache operation (`cache.get`, `cache.put`, `cache.remove`) |
| `db` (mongoose) | `mongoose.<Model>.<operation>` (`mongoose.BlogPost.findOne`) | The operation and the collection (`findOne blogposts`), the database namespace when there is no collection, or `mongodb` when the SDK has neither |

`navigation.redirect` spans are started through the same code path as navigation spans, so they get the same names.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

| `queue.process` | Integration-specific, sometimes containing per-message data (`my-queue process`, `order.created.12345 process`) | The messaging operation type and the destination (`process my-exchange`), or just the operation type when the destination has no name (`process`) |
| `queue.receive` | The kafkajs operation name (`poll my-topic`) | The messaging operation type and the destination (`receive my-topic`) |
| `cache.get`, `cache.put`, `cache.remove` | The cache key(s) (`user:123`), or for dataloader the operation and loader name (`dataloader.load usersLoader`) | The cache operation (`cache.get`, `cache.put`, `cache.remove`) |
| `db` (mongoose) | `mongoose.<Model>.<operation>` (`mongoose.BlogPost.findOne`) | The operation and the collection (`findOne blogposts`), the database namespace when there is no collection, or `mongodb` when the SDK has neither |

`navigation.redirect` spans are started through the same code path as navigation spans, so they get the same names.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.

Messaging span names now read `<operation type> <destination>` in every integration. The amqplib, kafkajs and NestJS BullMQ integrations used their own word order or verb, so their names change: `my-queue process` became `process my-queue`, amqplib's `publish` became `send`, and the kafkajs batch span's `poll` became `receive`. Cloudflare Queues and the kafkajs producer already matched the conventions, so their names are the same in both trace lifecycles. The operation name an integration reports upstream stays on `messaging.operation.name`.

Cache keys are unbounded, so they are no longer part of a cache span name. They remain available on the `cache.key` attribute, and every cache span now also carries a `cache.operation` attribute (`get`, `put`, `remove`) — the value the name is built from. That attribute is set in both trace lifecycles. This affects the redis/ioredis cache spans (`cachePrefixes`), the Nuxt and Nitro storage spans, and the dataloader spans.

A dataloader span no longer carries the loader's `name` either (`dataloader.load usersLoader` becomes `cache.get`), because the cache conventions have no slot for it in the name. It is reported on the `db.collection.name` attribute instead — a loader batches one entity type, so it is the closest thing dataloader has to a collection — and that attribute is set in both trace lifecycles. Unnamed loaders do not set it.

AWS SQS `SendMessage`, `SendMessageBatch` and `ReceiveMessage`, and SNS `Publish`, are messaging spans (e.g. `queue.publish`) rather than `rpc` ones now. Every other command on those clients, such as `DeleteMessage`, stays `rpc`. Their names follow the messaging conventions too, so the operation comes first (`my-queue receive` becomes `receive my-queue`, `my-topic send` becomes `send my-topic`). A streamed SNS `Publish` to a platform endpoint is named `send`, because the endpoint ARN it used to carry ends in a per-device id (`endpoint/GCM/myapp/<uuid> send`). The full ARN remains on `messaging.destination.name`.

An amqplib span's destination is the exchange it uses, or the routing key when it uses the default exchange. RabbitMQ binds every queue to the default exchange under a key equal to the queue's own name, so `sendToQueue` spans are named after their queue (`send my-queue`) instead of dropping the destination. `messaging.destination.name` reports the same value, and the routing key remains on `messaging.rabbitmq.destination.routing_key` in full.
