SQS Message Mover

sqsmover is a tool for moving AWS SQS messages from one queue to another. Useful when you need to move deadletter queue messages back into the original queue.

Features

• Reliable delivery. SQS Mover will only delete messages from the source queue after they were enqueued to the destination.
• Receives and sends messages in batches for faster processing.
• Progress indicator.
• User friendly info and error messages.
• Queue name resolution. For ease of use, you only need to provide a queue name and not the full arn address.
• Message attributes copy.
• Support for FIFO queues. MessageGroupId and MessageDeduplicationId are copied over to the destination messages.
• An optional flag to limit the number of messages to move.

Installing

SQS Mover is pre-compiled for macOS, Linux, Windows and does not require additional dependencies. You can install the pre-compiled binary (in several different ways) or compile from source.

Homebrew:

$ brew install sqsmover

Chocolatey (Windows)

$ choco install sqsmover

Shell script:

The following script will install the binary into /usr/local/bin

$ curl https://raw.githubusercontent.com/mercury2269/sqsmover/master/install.sh | sh

Note that you may need to run the sudo version below, or alternatively chown /usr/local/bin:

$ curl https://raw.githubusercontent.com/mercury2269/sqsmover/master/install.sh | sudo sh

From Source

Download:

git clone git@github.com:mercury2269/sqsmover.git && cd sqsmover

Run:

AWS_PROFILE=nbos-ris AWS_REGION=us-west-2 go run main.go --source transactions-dlq --destination transactions

Manually:

Download the pre-compiled binary from the releases page and copy to the desired location.

Set up AWS credentials

Specifying AWS credentials in either a shared credentials file or environment variables.

Option 1: Creating the Credentials File

If you don’t have a shared credentials file (~/.aws/credentials), you can use any text editor to create one in your home directory. Add the following content to your credentials file, replacing <YOUR_ACCESS_KEY_ID> and <YOUR_SECRET_ACCESS_KEY> with your credentials.

[default]
aws_access_key_id = <YOUR_ACCESS_KEY_ID>
aws_secret_access_key = <YOUR_SECRET_ACCESS_KEY>

The [default] heading defines credentials for the default profile, which the SQSMover will use unless you configure it to use another profile.

Optionally you can configure default region in ~/.aws/config

[default]
region=us-west-2

Option 2: Environment variables

As an alternative, you can setup AWS credentials in the environment variables.

The following examples show how to configure the environment variables.

Linux, OS X, or Unix

export AWS_ACCESS_KEY_ID=YOUR_AKID
export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY

Windows

set AWS_ACCESS_KEY_ID=YOUR_AKID
set AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY

Usage

sqsmover --help

usage: sqsmover --source=SOURCE --destination=DESTINATION [<flags>]

Flags:
  -h, --help                     Show context-sensitive help (also try
                                 --help-long and --help-man).
  -s, --source=SOURCE            The source queue name to move messages from.
  -d, --destination=DESTINATION  The destination queue name to move messages to.
  -r, --region="us-west-2"       The AWS region for source and destination queues.
  -e, --endpoint="https://..."   Use a specific endpoint in an AWS region. For more information see https://docs.aws.amazon.com/general/latest/gr/sqs-service.html
  -p, --profile=""               Use a specific profile from AWS credentials file.
  -l, --limit=0                  Limits total number of messages moved. No limit is set by default.
  -b, --batch=10                 The maximum number of messages to move at a time.
  -v, --version                  Show application version.

Examples:

Region will default to us-west-2, you can also override it with --region flag

sqsmover --source=my_source_queue_name --destination=my_destination_queuename
sqsmover --source=my_source_queue_name --destination=my_destination_queuename --region=eu-west-1

-- shorthand
sqsmover -s my_source_queue_name -d my_destination_queuename -r eu-west-1

Profile will default to Default, you can also override it with --profile flag

sqsmover --source=my_source_queue_name --destination=my_destination_queuename --profile=user

Limit number of moved messages to 10

sqsmover -s my_source_queue_name -d my_destination_queuename -l 10

By default, sqsmover will try to move 10 messages at a time. However, if the total size of messages in a batch exceeds 256kb (262,144 bytes) you will receive an error: Batch requests cannot be longer than 262144 bytes. You have sent x bytes. To resolve, reduce the batch size by setting -b flag.

sqsmover -s my_source_queue_name -d my_destination_queuename -b 3

Compiling from source

You will need to have Golang installed.

# clone it outside GOPATH
git clone https://github.com/mercury2269/sqsmover
cd sqsmover

# get dependencies using go modules (needs go 1.11+)
go get ./...

# build
go build -o sqsmover .

# check it works
./sqsmover --version
