Update DynamoDB Atomic Counter with Python / Boto

由 北战南征 提交于 2019-12-09 09:53:59
问题 I am trying to update an atomic count counter with Python Boto 2.3.0, but can find no documentation for the operation. It seems there is no direct interface, so I tried to go to "raw" updates using the layer1 interface, but I was unable to complete even a simple update. I tried the following variations but all with no luck dynoConn.update_item(INFLUENCER_DATA_TABLE, {'HashKeyElement': "9f08b4f5-d25a-4950-a948-0381c34aed1c"}, {'new': {'Value': {'N':"1"}, 'Action': "ADD"}}) dynoConn.update_item

问题 I'm using boto to spawn a new EC2 instance based on an AMI. The ami.run method has a number of parameters, but none for "name" - maybe it's called something different? 回答1: import boto c = boto.connect_ec2(ec2_key, ec2_secret) image = c.get_image(ec2_ami) reservation = image.run(key_name=ec2_keypair, security_groups=ec2_secgroups, instance_type=ec2_instancetype) instance = reservation.instances[0] c.create_tags([instance.id], {"Name": instance_name}) 回答2: In EC2 there's no api to change the

由 做~自己de王妃 提交于 2019-12-08 19:42:18
问题 I am using Django and S3Boto and whenever a signature has a '+' sign in it, I get a 403 Forbidden . If there is no '+' sign in the signature, I get the resource just fine.

Copying/using Python files from S3 to Amazon Elastic MapReduce at bootstrap time

由 孤街浪徒 提交于 2019-12-08 13:37:43
问题 I've figured out how to install python packages (numpy and such) at the bootstrapping step using boto, as well as copying files from S3 to my EC2 instances, still with boto. What I haven't figured out is how to distribute python scripts (or any file) from S3 buckets to each EMR instance using boto. Any pointers? 回答1: If you are using boto, I recommend packaging all your Python files in an archive (.tar.gz format) and then using the cacheArchive directive in Hadoop/EMR to access it. This is
