下面是一个使用AWS Glue输出一个带有分区的文件的代码示例:
import boto3
import sys
# 创建Glue客户端
glue_client = boto3.client('glue')
# 创建分区的元数据
partition_values = {'partition_column_name': 'partition_value'}
partition_input = {'Values': [partition_values]}
# 创建输出目标的元数据
output_location = 's3://bucket-name/output/'
output_writer = {'S3Writer': {'BucketName': 'bucket-name', 'Prefix': 'output/'}}
# 创建输出目标
glue_client.create_partition(
DatabaseName='database-name',
TableName='table-name',
PartitionInput=partition_input,
PartitionValues=[partition_values]
)
# 创建ETL作业
job_response = glue_client.create_job(
Name='output-partitioned-file-job',
Role='AWSGlueServiceRole',
Command={'Name': 'glueetl', 'ScriptLocation': 's3://bucket-name/scripts/script.py'},
DefaultArguments={'--job-language': 'python'},
Connections={'Connections': ['connection-name']},
MaxCapacity=2.0,
MaxRetries=2,
Timeout=10,
WorkerType='Standard',
NumberOfWorkers=10,
ExecutionProperty={'MaxConcurrentRuns': 5},
GlueVersion='1.0'
)
# 创建ETL作业的输出
glue_client.create_job_run(
JobName='output-partitioned-file-job',
Arguments={'--output_location': output_location},
AllocatedCapacity=10,
Timeout=2880,
WorkerType='Standard',
NumberOfWorkers=10
)
请根据您的实际情况修改上述代码中的参数,以适应您的AWS Glue作业和输出要求。
