It should be possible to change the CloudWatch lookback window start point configurable. Currently all data fetched from CloudWatch are 15 minutes old (we're fetching data in a window between 15-10 minutes from now()).
See the discussion in #168 for details.
Refactored the CloudWatch metrics fetching #192
Changed some values from sec to min #192
Implemented lookback-window-start option #192
@aulisse I have now implemented an option to make it possible to configure the lookback window. There's an new option (on GSI and table level) called lookback-window-start.
I haven't tested it at all and I might change the option name, but if you want to testing you can install dynamic-dynamodb 1.18.0a1 via pip:
pip install dynamic-dynamodb==1.18.0a1
I'll do some testing and release this within the next few days, but likely not today as I am currently travelling.
Fixes problem reading config option #192
Fixed issue in lookback window for GSIs #192
