Thank you very much for the nice explanation, loved it. Would like to request you one more detailed video of Glue ETL for SCD type 1 (merge upsert) type logic on s3 to S3
Is that possible to debug the code which you developed in the video in VS Code or pycharm IDE by setting aws creds in your IDE locally instead of running on console?
Hi Manuka - This is a good video because normally no one touches the scripting part of it. Even the AWS documentation is missing that. So kudos to you for presenting the grey region. Also, I have been trying to emulate certain ETL use cases from Informatica to Glue and I am thinking if it makes sense to first create a dynamic dataframe from the glue catalog --> convert to dataframce --> do all the transformations like Trimming, date format conversion, creating new columns(with case statement logics) etc etc and then finally convert it back to dynamic frame and then write it back to the catalog table. does that sound reasonable?
Excellent excellent video. There are not many good videos that explains AWS Glue basic programs. I am pretty new to AWS Glue and trying to create an upsert job that will insert else update my data present in a Redshift table and source is a csv file on S3. Can you please post a video that will explain how upsert works in Glue? Thanks in advance!
Hi thanks for the great video. I have learnt that recently AWS has given full setup to execute glue job locally. It would be of great help if you can make the same setup on visual studio code and create a video of the same. There no documentation or setup steps any where.
Very helpful.. just one thing i have four sql tables and want create four parquet files with respective that tables. So for that can i create four python script job or handle in one script file using looping.? please advise me.
Simply can run the job on a single script instead of running multiple scripts. Complete read source table and write of parquet file one after another to avoid loss all read data in the case of job failure.
First, convert the dynamic frame to Spark Dataframe --------------------------------- datasource0 = datasource0.toDF() Then add a new column to spark data frame. Use spark user defined function to extract value from json object. --------------------------------- from pyspark.sql.functions import udf getNewValues = udf(lambda val: val+1) # you can extract value from json here instead of val+1 datasource0 = datasource0.withColumn('New_Col_Name', getNewValues(col('existing_col'))
Really useful tutorial! Thank you! Just wondering what I should do if I need to import another python script such as `import script2`, how should I setup in the job config? I've tried to store this script in s2 bucket and add the location in 'Security configuration, script libraries, and job parameters (optional)'->'Python library path', but it gave me error `ModuleNotFoundError: No module named 'script2`, does anyone know how to fix this? Thanks.
If your python script is just a single python file (ibb.co/HB6grhL), Upload it to the S3 bucket and add the S3 path as a glue job's python library path. (ibb.co/PgPrLCx) First, make sure your Glue job's IAM role has access to S3. Then you need to add import statements on top of the script file to use definitions on the external script file. (ibb.co/23Kx0vp)
You can use the python shell for general purpose python script which You can use these jobs to schedule and run tasks that don't require an Apache Spark environment.
Hey Marlon, there is no direct way to deploy your python script from ide on the local machine. What I have done is to create a work space on vs code with AWS glue python library file which helps us to get the advantage of IntelliSense. Then after that implementation is done, I just copy and paste the script to AWS glue console
@@CalceyTech Hi, thanks for the reply! That's what I meant to ask, sorry. My actual question now is how can I get the awsglue library in VS code in order to get the advantage of IntelliSense? I tried pip install awsglue..
@@marlonholland955 First clone AWS Glue python library repository - github.com/awslabs/aws-glue-libs. Then copy the awsglue folder from cloned content into your working workspace. Finally, create a new python file(custom-script.py) within the workspace. Hereafter, you'll able to use python imports from AWS glue within your custom script files in your workspace
It seems that once aws-glue-libs is installed, glue scripts are to be placed there as well. 4 me this fixed the moduleNotFound error even though everything is installed.
You should be able achieve it using the same flow in this tutorial with some changes to the data extraction step. Use a JDBC driver for ElasticSearch instead.
Hi Friend, Great Work. I have 1 question for you. I have data to get it from 2 tables with join. E.g. users_table and users_add_table (both having one is to one mapping) join on user_id Which is the best way of the following?? 1. Get users_table_df and users_add_table_df, then Join.apply on user_id to get the final dataFrame 2. glueContext.read.format("jdbc") .option("driver", jdbc_driver_name).......... .option("dbtable", YOUR_QUERY) In the 2nd approach i have written SQL joins in YOUR_QUERY
I think performance-wise 2nd option is better. In the data frame approach, there are a lot of python objects involved to compute the result and execute 2 DB queries to bring the final result. In the SQL approach, everything is done in-memory.
Hi, I am trying to perform ETL in Glue and I am using the snowflake-connector-python module. it shows module error as it cannot import the module, can you please tell me how can I use the custom libs of python in glue? Thanks

First, take a clone from github.com/awslabs/aws-glue-libs. Open an empty workspace from VSCode. Then copy "awsglue" folder from the cloned repository to the VSCode workspace as I have done in the video.
@@CalceyTech Thank you for your reply.Yes i have done that and getting an error: "ModuleNotFoundError: No module named 'dynamicframe'". Do I need to install the spark distribution in my local? I have already installed the pyspark client.
HELLO BRO, I have created job and updated script As per your tutorial but I am getting an error saying that "connection Timedout". Please see full error message "com.amazon.support.exceptions.GeneralException: [Amazon](500150) Error setting/closing connection: Connection timed out.' ..... Please advise what else I missed. thanks
Actually this issue is not related to your GLUE script. It seems like the AWS environment that is running your Glue script does not have permission to access your external or internal database using DB information you have provided into the script. Because of that AWS automatically cut off the connection with time out error.
AWS Glue ETL jobs can interact with a variety of data sources inside and outside of the AWS environment. For optimal operation in a hybrid environment, AWS Glue might require an additional network, firewall, or DNS configuration.
