CheckpointStore

建構函式

CheckpointStore()

方法

claim_ownership	嘗試宣告指定資料分割清單的擁有權。
list_checkpoints	列出所選儲存體服務的更新檢查點。
list_ownership	從所選的儲存體服務擷取完整的擁有權清單。
update_checkpoint	使用所選儲存體服務中位移、相關聯分割區和取用者群組的指定資訊，更新檢查點。 注意：如果您打算實作自訂檢查點存放區，以在跨語言 EventHubs SDK 之間執行，建議您將位移值保存為整數。

claim_ownership

嘗試宣告指定資料分割清單的擁有權。

abstract claim_ownership(ownership_list: Iterable[Dict[str, Any]], **kwargs: Any) -> Iterable[Dict[str, Any]]

參數

名稱	Description
ownership_list 必要	Iterable[Dict[str,Any]] 可逐一查看包含要宣告之所有擁有權的字典。

update_checkpoint

使用所選儲存體服務中位移、相關聯分割區和取用者群組的指定資訊，更新檢查點。

注意：如果您打算實作自訂檢查點存放區，以在跨語言 EventHubs SDK 之間執行，建議您將位移值保存為整數。

abstract update_checkpoint(checkpoint: Dict[str, str | int | None], **kwargs: Any) -> None

參數

名稱	Description
checkpoint 必要	Dict[str,Any] 包含檢查點資訊的聽寫： fully_qualified_namespace (str) ：事件中樞所屬的完整命名空間。 格式就像 「.servicebus.windows.net」。 eventhub_name str (str) ：與檢查點相關聯的特定事件中樞名稱，相對於包含檢查點的事件中樞命名空間。 consumer_group (str) ：檢查點相關聯的取用者群組名稱。 partition_id (str) ：建立檢查點的分割區識別碼。 sequence_number (int) ：新檢查點的 EventData 序號將會與相關聯。 offset (str) ：新檢查點的 EventData 位移將會與相關聯。
