Thank you for watching my videos. Did you check the code file that I shared in description it has logic to read env variable and you need set the variables as well.
Thank you for watching my videos. May be you need to check if S3 bucket vpc endpoint interface is enabled or not here and also make sure that AWS lambda is integrated with VPC.
Thank you for watching my videos. Here IAM role is for AWS Lambda service role which gets invoked during file upload in S3 bucket. And IAM user credentials are for SQL 'COPY' command run to copy data from s3 bucket to Amazon Redshift cluster table. Watch again hope you get this. Happy learning.
Thank you for watching videos. As it is event driven it should work in that case as well. But if there are any error , it could be handled in code. Let me know if you face any errors in these cases.
Thank you for watching my videos. Following could be the reasons. 1. Check if you have have trigger from S3 bucket object creation is added or not 2. Check if Lambda role has the trust to AWS Lambda service.
@@cloudquicklabs I will double check . Thanks much . I also got an error saying psycopg2 does not have attribute connect error while testing the lambda . I am using Python run time 3.7 , I am not sure what caused this issue ?

Sorry to sound like a broken record. I am still very confused. Basically, If i am reading it correctly, we need to create a IAM user with redshift access and pass the creds for that IAM role to the query string. Do we need to supply some special roles to the lambda itself? Does the IAM role need to have some permission over lambda?
Thank you for watching my videos. Here I have used acess_secrete and acess_key as Lambda environment variables. You can trying following docs.aws.amazon.com/lambda/latest/dg/configuration-envvars.html
Thank you for watching my videos. Please check the video descriptions where I have given the link of 'psycopg' package to create the required Lambda layer and this helps to import the module. I encourage to go through the video again.
I am getting error message in cloud watch log events after uploading my CSV file in s3 like "[ERROR] InternalError_: The specified S3 prefix 'Weather+readings+Analysis.csv' does not exist".
Please enable vpc endpoint for s3 service of type gateway. Then it should be working. Because here VPC is private network and S3 become public so it is not able to communicate, I believe adding endpoints will solve the issue here. Do let me know if you still facing the issues further
Okay it looks file name issue - is it possible to change file name to 'WeatherReadingAnalysis.csv' as it looks to S3 url with spaces name is the issues
Thank you for sharing the video, this works. Please let me know how can i ignore the header while using this code also how can i load a tsv i.e Tab separated file using the code. It will be helpful.
Thank you for watching my videos. As we are loading data with lambda, you can ignore first row with code tactics. To load tsv files first converts to csv files which is easy then you can follow same steps mentioned in this video. www.google.com/amp/s/www.geeksforgeeks.org/python-convert-tsv-to-csv-file/amp/
Hi sir, First of all, I would like to say thank you for sharing such wonderful tutorial video with the code, great video lecture. Looking forward to see some more videos on AWS Glue, EMR, Athena, EC2 as well. I am unable to download the zip file from hit repo, is there anything you can suggest ?
thanks for video, i have the following problem when executing the lambda function, I get this error "Unable to import module 'LambdaTest::LambdaTest': No module named 'LambdaTest::LambdaTest"
Thank you for watching my videos. I believe you have created the lambda as suggested in video, please try to recreate the Lambda with runtime python 3.7 and also creat the lamba layer using same python.zip folder that I have shared and you must attach same on lamba created.
Try creating the lambda first with 'Author from scratch' option using aws console, then copy paste the code that I have given in repo link.. It should work this way.
