Your way of explanation was awesome. I have seen many videos related to SQS and Lambda but you have explained everything step by step very clearly. Thank you very much.
I have a doubt while connecting to DynamoDB you have given the apiVersion from where can you get that? If you give me replay it's a great help for me.

[@lovetocode4486]

Hi Prasanthi,
Thanks for you comments. Love it.
There are two ways you can deal with DynamoDB tables. One way is using "new AWS.DynamoDB()" and other way is "new AWS.DynamoDB.DocumentClient();"
The "DocumentClient" is wrapper for "AWS.DynamoDB()". The "DocumentClient" is working as more natural way.
To your question regarding "apiVersion", you don't necessarily provide the `apiVersion`. Honestly I can't remember where is the apiVersion is mentioned.
BTW you can still use DocumentClient without specifying the apiVersion.
Furthermore I have put some code to understand the different. Hope this helps
// using "DynamoDB client":
var params = {
Item: {
"AlbumTitle": {
S: "AAAA
},
"Artist": {
S: "John"
},
"SongTitle": {
S: "Cheap Trills"
}
},
TableName: "Music"
};
dynamodb.putItem(params, function (err, data) {
if (err) console.log(err)
else console.log(data);
});
// Using "DocumentClient"
var params = {
Item: {
"AlbumTitle": "AAAAA",
"Artist": "John",
"SongTitle": "Cheap Trills"
},
TableName: "Music"
};
var documentClient = new AWS.DynamoDB.DocumentClient();
documentClient.put(params, function (err, data) {
if (err) console.log(err);
else console.log(data);
});

hi there i am new to aws and cloud computing and i was wondering whether this same application can be done with the lambda function based on python?

[@lovetocode4486]

Hi mate,
Yes, obviously you can do with most of languages. Python is one of them.

@@lovetocode4486 finding it a little diffiult as the syntax(s) are creating little confusion, if you could help me with this, it would help me a lot

[@lovetocode4486]

Hey mate, seems the event is not valid. Could you pls validate the payload. It should be a valid json.
