Hi Rahul, I have learned a lot from your videos. I have a request for you to create a video on dependency injection in lambda functions and Environment variables in lambda functions
Thank you Saghar for the suggestion. Added it to my list, will do something soon. What are you looking for in Environment Variables? I have a video on Parameter Store and Secrets Manager in my series here, which is what I prefer more for storing configurations Series - bit.ly/aws-net-series www.rahulpnath.com/blog/aws-secrets-manager/ www.rahulpnath.com/blog/aws-parameter-store/
@@RahulNath Thanks for the reply. Regarding environment variables, we have two options either use appsettings.json or have options on the lambda configuration in the AWS console. The use case is like a lambda function putting something in the SQS and SQSURL and other settings reading from there.
@@sagharfrancis8091 Any reason you don't want to use Parameter Store or Secrets manager? If the configs are sensitive recommend using them. What problem are you facing using the appsetting.json?
Hi Rahul I have learned a lot from your vidoes .Imazing content and very simple , One request can u make video for dynamodb for two or three tables and how to join and query
Thank you Renu and glad you find the content useful. Normally you wouldn't query across multiple tables at least not with a join, since each would have their own partition/sort key. Can you provide more details on your use case, so that it might help understand the problem. Feel free to drop an email as well, if it's too long for a comment (hello@rahulpnath.com)
CityName is partition and DateTime is hash key - I have an associated blog article here that might help www.rahulpnath.com/blog/dynamodb-querying-dotnet/ Can you elaborate on duplicate data part? Also the example is less about key design and more on ways to query. Depending on your data and read patterns you will need to model your keys appropriately. This article is a good start docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-design.html Let me know if you have additional questions.
Thank you Ivan!! Yes I struggle with some pronunciation and often get it mixed up, will keep this one in mind! Hope you are enjoying the DynamoDB Series bit.ly/awsdynamodb
Hi Rahul, Thank you for the videos, they are of great help. I'm just struggling with a filterexpression though, how can I properly implement a "contains" query? I'm trying with FilterExpression and not coming right Your help would be much appreciated
Glad you are finding the videos useful. Could you provide more details on your scenario and what you are trying to do , the keys in the table etc. Hopefully I can try and help you then 👍
@@RahulNath I have a primary key and sort key that I use to identify rows belonging to a user, with a number of attributes as well and in this case I have a message column that stores chat text. So I’m trying to filter from the results, records that contain a particular string value in the message text. Does it make sense? Something like select where Message contains ‘Rahul’ 😅
as always, great video!
Thanks again Mariano for your support!

Great lesson. I wonder if you could do the same for cloudsearch query. Thank you
Great suggestion! I will add it to my list

Hi Rahul, i saw you set Cityname (string) is Partition key, but why you can used duplicate data ? how you create on your table ?

@@RahulNath thank you for explained now i understand it.:) CityName + DateTime is hash key, but i think time it's not duplicate.
Good video
Glad you like it Piyali! and hope you are enjoying the recent videos on DynamoDB. Do let know if you have topic suggestions.
Great content, FYI - iteration is pronounced, It - ter- ation.

Getting an InvalidOperationException: Must have one range key or a GSI index defined for the table. My table has no range key
Can you provide more details and the code you are using?
@@RahulNath I figured that out too. The problem was in table creation. I added global indexes while creating table and that worked
