I'm trying to disable down scaling altogether, but setting the following results in down scaling still happening..

In the config file (please let me know if you want to full block of config for this table):

# Enable reads up or down scaling
# Note: Those controls will not have any effect if enable-reads-autoscaling is false
enable-reads-up-scaling = true
enable-reads-down-scaling = false

# Enable writes up or down scaling
# Note: Those controls will not have any effect if enable-writes-autoscaling is false
enable-writes-up-scaling = true
enable-writes-down-scaling = false

When I start dynamic-dynamodb:

This is happening when running 1.19.0. Help! :)

To be clear, this is the SNS notification we got:

mytable - Reads: DOWN from 90 to 81
mytable - Writes: DOWN from 100 to 90

I don't see 1.19.1 available yet, have you already released it?
