# Table Autoscaling Configuration
#
# ** There is an outstanding issue with the serverless-dynamodb-autoscaling plugin
#   where attempting to provision auto scaling watches on multiple tables at once, fails in cloudformation.
#   For now, I'm only enabling for loans table.
#   When issue is resolved, uncomment the config for the other tables.
