sqspipe

sqspipe continuously moves messages between aws sqs queues in a rate limited manner.

Features

  • Use case is to put a rate limit in between SQS messaging.
  • May be handy to move all messages from one queue to another in a single shot.
  • One is supposed to run a single instance of sqsqueue. If you run multiple instances (like in multiple pods replicas), every instance will deliver the maximum configured rate.
  • Moving messages across regions is supported.
  • Moving messages across accounts is supported.
  • Health check endpoint: http://localhost:2000/health
  • Prometheus metrics endpoint: http://localhost:3000/metrics

Build

git clone https://github.com/udhos/sqspipe
cd sqspipe
go install ./sqspipe

Run

export QUEUE_URL_SRC=https://sqs.us-east-1.amazonaws.com/111111111111/queue_src
export QUEUE_URL_DST=https://sqs.us-east-1.amazonaws.com/222222222222/queue_dst
sqspipe

Mandatory Env Vars

sqspipe will move messages from source queue defined in $QUEUE_URL_SRC to destination queue defined in $QUEUE_URL_DST.

These env vars are required.

export QUEUE_URL_SRC=https://sqs.us-east-1.amazonaws.com/111111111111/queue_src
export QUEUE_URL_DST=https://sqs.us-east-1.amazonaws.com/222222222222/queue_dst

Optional Env Vars

These env vars are optional.

export ROLE_ARN_SRC=arn:aws:iam::111111111111:role/sqs_consumer
export ROLE_ARN_DST=arn:aws:iam::222222222222:role/sqs_producer
export MAX_RATE=16 ;# max messages per second
export HEALTH_ADDR=:2000
export HEALTH_PATH=/health
export METRICS_ADDR=:3000
export METRICS_PATH=/metrics
Roles

You can use $ROLE_ARN_SRC to specify a role to access the source queue, and $ROLE_ARN_DST to specify a role to access the destination queue. The role in $ROLE_ARN_SRC must allow actions sqs:ReceiveMessage and sqs:DeleteMessage to source queue. The role in $ROLE_ARN_DST must allow action sqs:SendMessage to destination queue.

Max Rate

If $MAX_RATE isn't specified, it defaults to 16 messages per second.

Health check

You can use these environment variables to define the health check endpoint.

HEALTH_ADDR=:2000
HEALTH_PATH=/health

Metrics

You can use these environment variables to define the metrics endpoint.

METRICS_ADDR=:3000
METRICS_PATH=/metrics

The metrics endpoint exposes the variables below.

# HELP sqspipe_delete_error_total Number of SQS DeleteMessage errors.
