Amazon Web Services 文档中描述的 Amazon Web Services 服务或功能可能因区域而异。要查看适用于中国区域的差异,请参阅 中国的 Amazon Web Services 服务入门 (PDF)

要获得与亚马逊 Timestream 类似的功能 LiveAnalytics,可以考虑适用于 InfluxDB 的亚马逊 Timestream。它为实时分析提供了简化的数据摄取和个位数毫秒的查询响应时间。点击此处了解更多。

描述批量加载任务

您可以使用以下代码片段来描述批量加载任务。

Java
public void describeBatchLoadTask(String taskId) { final DescribeBatchLoadTaskResponse batchLoadTaskResponse = amazonTimestreamWrite .describeBatchLoadTask(DescribeBatchLoadTaskRequest.builder() .taskId(taskId) .build()); System.out.println("Task id: " + batchLoadTaskResponse.batchLoadTaskDescription().taskId()); System.out.println("Status: " + batchLoadTaskResponse.batchLoadTaskDescription().taskStatusAsString()); System.out.println("Records processed: " + batchLoadTaskResponse.batchLoadTaskDescription().progressReport().recordsProcessed()); }
Go
package main import ( "fmt" "context" "log" "github.com/aws/aws-sdk-go-v2/aws" "github.com/aws/aws-sdk-go-v2/config" "github.com/aws/aws-sdk-go-v2/service/timestreamwrite" ) func main() { customResolver := aws.EndpointResolverWithOptionsFunc(func(service, region string, options ...interface{}) (aws.Endpoint, error) { if service == timestreamwrite.ServiceID && region == "us-west-2" { return aws.Endpoint{ PartitionID: "aws", URL: <URL>, SigningRegion: "us-west-2", }, nil } return aws.Endpoint{}, &aws.EndpointNotFoundError{} }) cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithEndpointResolverWithOptions(customResolver), config.WithRegion("us-west-2")) if err != nil { log.Fatalf("failed to load configuration, %v", err) } client := timestreamwrite.NewFromConfig(cfg) response, err := client.DescribeBatchLoadTask(context.TODO(), &timestreamwrite.DescribeBatchLoadTaskInput{ TaskId: aws.String("<TaskId>"), }) fmt.Println(aws.ToString(response.BatchLoadTaskDescription.TaskId)) }
Python
import boto3 from botocore.config import Config INGEST_ENDPOINT="<url>" REGION="us-west-2" HT_TTL_HOURS = 24 CT_TTL_DAYS = 7 TASK_ID = "<task id>" def describe_batch_load_task(client, task_id): try: result = client.describe_batch_load_task(TaskId=task_id) print("Successfully described batch load task: ", result) except Exception as err: print("Describe batch load task job failed:", err) if __name__ == '__main__': session = boto3.Session() write_client = session.client('timestream-write', \ endpoint_url=INGEST_ENDPOINT, region_name=REGION, \ config=Config(read_timeout=20, max_pool_connections = 5000, retries={'max_attempts': 10})) describe_batch_load_task(write_client, TASK_ID)
Node.js
