SQS - Truck

Provides a way to send messages over 256kb. Provides a send and read function for handling this case.

If you try to send a message that is higher than the defined limit, it is sent to the store (it supports s3) and generated an id that will be the body content and adds in the header the store used. When it reads a valid message if it has in the header the store, if it exists it obtains the content and places it in the body of the message sqs.

Example

package sqstruck

import (
	"os"
	"testing"

	"github.com/Tlantic/sqstruck"
	strucks3 "github.com/Tlantic/sqstruck/s3"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/service/sqs"
)

func Test_PrepareWrite(t *testing.T) {

	data := &sqs.SendMessageBatchRequestEntry{
		Id:                aws.String("1112222"),
		MessageBody:       aws.String(string("ola tudo bem")),
		MessageAttributes: make(map[string]*sqs.MessageAttributeValue),
	}

	data.MessageAttributes["_aggregateId"] = &sqs.MessageAttributeValue{
		DataType:    aws.String("String"),
		StringValue: aws.String("event.AggregateId222224444"),
	}

	data.MessageAttributes["_id"] = &sqs.MessageAttributeValue{
		DataType:    aws.String("String"),
		StringValue: aws.String("asdfghjkl"),
	}

	os.Setenv("AWS_ACCESS_KEY_ID", "asdsads")
	os.Setenv("AWS_SECRET_ACCESS_KEY", "asdas")

	st, _ := strucks3.New("s3://eu-west-1/sqstruckstore/")

	struck := sqstruck.New(10, st)
	struck.PrepareWrite(data)

	dataMsg := &sqs.Message{
		MessageAttributes: make(map[string]*sqs.MessageAttributeValue),
	}

	dataMsg.MessageAttributes["_s3"] = &sqs.MessageAttributeValue{
		DataType:    aws.String("String"),
		StringValue: aws.String("asdfghjkl"),
	}

	struck.PrepareWrite(data)

	msg, _ := struck.PrepareRead(dataMsg)

	t.Log(msg)
}
