How to Add DynamoDB to my Redash


From Redash home page i see one of the supported Data source is DynamoDB. Could you please throw more light on how to configure DyanmoDB to Redash?


You need to make sure that:

  1. You have a recent enough version (v0.11).
  2. That you have installed the needed Python dependencies.


Could you please through more light on this? I believe there is more configuration to be done to use the right vpn details


What are the python dependencies. I installed redash using the install script downloaded from the redash site.


Not sure what the install script does, but you need not only to (pip) install the requirements.txt but also the requirements_all_ds.txt (“all datasources”). With that you get all “missing” datasources like dynamodb, mysql, influxdb, etc …


hmm just saw in another thread that you (@chiddu) obviously solved you question yourself. Why don’t you help others by answering you question yourself then ?


No, I have not solved it. I think it has something to do with the connectivity. all the required packages have been installed, I verified that.


I getting a Connection Test Failed when try to connect to DynamoDB

Failed 254007: The certificate attached is not for OCSP signing.
I’m running in AWS instance
Redash 1.0.3+b2850


There was another user having this problem, but I couldn’t reproduce it. How did you setup Redash?


@arikfr I am having similar issue. I am using AWS AMI.

Connection Test Failed: 254007: The certificate attached is not for OCSP signing.

After installation is there any setup is required?


I’ve just received the same - brand new AMI (1.0.1+b2833). This happens on both queries and when testing the data connection. This box is in a VPC with a private IP address (but access to the internet).

I am getting this too when I try to add a dynamo data source.


I had this error got it working by upgrading snowflake-connector-python


@binary upgrading snowflake-connector-python solved your DynamoDB issues or you had the same error with a Snowflake connection?


When adding a DynamoDB data source I got the Failed 254007: The certificate attached is not for OCSP signing. error. Upgrading snowflake-connector-python fixed the error.


@binary is correct the problem is indeed caused by the snowflake-connector :unamused: You can either upgrade it, or add to your .env file:

export REDASH_DISABLED_QUERY_RUNNERS="redash.query_runner.snowflake"

And then restart all Redash services. This will prevent Redash from loading the Snowflake connector.
