[Discussion] Strategy with fixed values. about dynamodb-lambda-autoscale

You should just be able to specify the min and max to the same value and that's it, if that's not working then that would be a bug. I don't think I would change it to fixed as it would only save a single line in that case... Am I understand you correctly?

Hi Tom,

When you use the min and max values alone, no increment or decrements to that value are performed due to the following code blocks such as in the isReadCapacityIncrementRequired function in the Provisioner.js file line 50:

if (config.ReadCapacity.Increment == null) {
     return false;
}

When adding an "Increment" or "Decrement" attrbute you also seem to need at least a "To" attribute and an empty "When" block. Otherwise either no change is performed or "not defined errors" occur.

Small update, the minimum required configuration for a working fixed value currently is:

{
  "ReadCapacity": {
    "Min": 1,
    "Max": 1,
    "Increment":{
      "When":{}
    },
    "Decrement":{
      "When":{}
    }
  },
  "WriteCapacity": {
    "Min": 1,
    "Max": 1,
    "Increment":{
      "When":{}
    },
    "Decrement":{
      "When":{}
    }
  }
}

Ok that's a bug then, I'm making some other changes at the moment and I'll put a fix in for this also. Thanks

Just checked a fix, should work now
