Issue with JSON generated by TDynamoDBInput

Hi, thanks in advance for your support and responses


We are using the TDynamoDBInput component to connect to a Dynamo DB table and dump the records.

The JSON which gets dumped is of the below format (Please note this is indicative and not actual values)


{key1 = { key2=value2 , key3=value3}}


Now the issue faced by us is that this is not identified as a valid JSON by Redshift Spectrum or any JSON parsing tool

since an ideal JSON would be

{"key1" : { "key2":"value2" , "key3":"value3"}}


( Note the double quotes / Colon which are required in a well structured JSON)


Are we doing something incorrect. Can you please guide.

As such the generated JSON by DynamoDB input cannot be used by any tool which parses JSON.

Re: Issue with JSON generated by TDynamoDBInput

I just fought with this same issue.  DynamoDB uses what it calls DynamoDB JSON, which is not formatted like a classic JSON string.  What I ended up doing was using the tReplace connector to reformat the JSON string into something usable and then used tExtractJSONFields to break down the JSON string into it's usable parts.

Hi all, 

unfortunately I'm facing the same problem, tested with V7.3.1.M3.

This bug is still not fixed.


@xdshi Can you please add it to your bugtracker and suggest it for implementing the correct quotings within the final V7.3.1 version?


Many thanks in advance!
