I am learning about a wonderful tool called AWS Cloudformation and I am having a hard time finding resources to find how to trigger AWS Gluejob via SQS.
I learnt about Glue Triggers from here. How do I trigger a gluejob whenever something is dumped in SQS?
Any help or guidance is appreciated.
There is currently no possibility of SQS triggering a Glue job directly.
What you could do though, is writing a Lambda function, which gets triggered by your SQS.
In this Lambda function you could call the Glue SDK to start your Glue Job.

I have an AWS Python lambda function that connects to a DB, checks data integrity and send alerts to a slack channel(that's already done).
I want to execute that lambda every XX minutes.
What's the best way to do it?
You can build this with AWS EventBridge.
The documentation contains an example for this exact use case:

I'm looking to trigger a glue job from SNS without using Lambda. Is this possible?
I am new with AWS and don't know how to do the following. When I put an object in S3 I want to launch a python script that does some transformations and returns it to another path in S3. I've tried a lambda function but the process takes more than 300 seconds. I've also tried it with a Glue job but I don't know how to trigger it when I put the file in S3.
Does anyone know how to do it? Maybe I'm using the wrong AWS tools.
The simple solution for your problem is here:
Since you've already mentioned that you have AWS Glue job working to do this operation. And all you don't know is how to trigger glue job when file placed in s3, I am answering to that question.
You can write an AWS lambda using boto3 module which can be triggered based up on the s3 event and have setup glue.start_job_run command in your lambda function.
response = client.start_job_run(
JobName='string')
https://boto3.readthedocs.io/en/latest/reference/services/glue.html#Glue.Client.start_job_run
Note:: I strongly believe Glue is the right tool rather than lambda for your requirement that you mentioned in question, because AWS lambda have time out limitation. It will get timeout after 300 seconds.
One option would be to use SQS:
Create the SQS queue.
Setup S3 to send notifications to the SQS queue when new objects are added to the source bucket. See Configuring Amazon S3 Event Notifications.
Setup your Python script on an EC2 instance and listen to the SQS queue in your code.
Upload the output of your Python script into the target S3 bucket after script finished.
Can you break up the Python processing into smaller steps? I'd definitely recommend that you use Lambda instead of managing EC2 if you can get your code to run within the Lambda restrictions.
I'm trying to figure out how to automatically kick off an AWS Glue Job when an AWS Glue Crawler completes. I see that the Crawlers send events when they complete, but I'm struggling to parse through the documentation to figure out how to listen to that event and then launch the AWS Glue Job.
This seems like a fairly simple question, but I haven't been able to find any leads so far. I'd appreciate some help. Thanks in advance!
You can create a CloudWatch event, choose Glue Crawler state change as Event source, choose a Lambda function as Event target, and in the Lambda function you can use boto3(or other language sdk) to invoke the job to run.
Use a AWS Glue Trigger.
For anything involving more than two steps, I'd recommend using AWS Glue Workflows. They are formed by chaining Glue jobs, crawlers and triggers together into a workflow that can be visualised and monitored easily.
I am working with PHP technology.
I have my program that will write message to Amazon SQS.
Can anybody tell me how I can use lambda service to get data from SQS and push it into MySQL. Lambda service should get trigger whenever new record gets added to the queue.
Can somebody share the steps or code that will help me to get through with this task?
There isn't any official way to link SQS and Lambda at the moment. Have you looked into using an SNS topic instead of an SQS queue?
Agree with Mark B.
Ways to get events over to lambda.
use SNS http://docs.aws.amazon.com/sns/latest/dg/sns-lambda.html
use SNS->SQS and have the lambda launched by the sns notification just use it to load whatever is in te SQS queue.
use kinesis.
alternatively have lambda run by cron job to read sqs. Depends on needed latency. If you require it be processed immediately then this is not the solution because you would be running the lambda all the time.
Important note for using SQS. You are charged when you query even if no messages are waiting. So do not do fast polls even in your lambdas. Easy to run up a huge bill doing nothing. Also good reason to make sure you set up cloudwatch on the account to monitor usage and charges.
