Example configuration file

This is a full example of a Dynamic DynamoDB configuration file. :

[global]
# AWS access keys
aws-access-key-id: AWS_ACCESS_KEY
aws-secret-access-key-id: AWS_SECRET_KEY

# AWS region to use
region: us-east-1

# How often should Dynamic DynamoDB monitor changes (in seconds)
check-interval: 300

# Circuit breaker configuration
# No provisioning updates will be made unless this URL returns
# a HTTP 200 OK status code
#circuit-breaker-url: http://my.service.com/v1/is_up
#circuit-breaker-timeout: 500

[logging]
# Log level [debug|info|warning|error]
log-level: info

# Log file (comment out to get only console output)
log-file: /var/log/dynamic-dynamodb.log


[table: my_table]

# Read provisioning configuration

# Thresholds for scaling up or down the provisioning (%)
reads-upper-threshold: 90
reads-lower-threshold: 30

# How many percent should Dynamic DynamoDB increase/decrease provisioning with (%)
increase-reads-with: 50
decrease-reads-with: 50

# Units to increase or decrease reads with, must be either percent or units
increase-reads-unit: percent
decrease-reads-unit: percent

# Maximum and minimum read provisioning
# Dynamic DynamoDB will not provision any more or less reads than this
#min-provisioned-reads: 100
#max-provisioned-reads: 500

#
# Write provisioning configuration

# Thresholds for scaling up or down the provisioning (%)
writes-upper-threshold: 90
writes-lower-threshold: 30

# How many percent should Dynamic DynamoDB increase/decrease provisioning with (%)
increase-writes-with: 50
decrease-writes-with: 50

# Units to increase or decrease writes with, must be either percent or units
increase-writes-unit: percent
decrease-writes-unit: percent

# Maximum and minimum write provisioning
# Dynamic DynamoDB will not provision any more or less writes than this
#min-provisioned-writes: 100
#max-provisioned-writes: 500

#
# Maintenance windows (in UTC)
#
#maintenance-windows: 22:00-23:59,00:00-06:00

#
# Other settings
#

# Allow down scaling when at 0% consumed reads
#allow-scaling-down-reads-on-0-percent: true
#allow-scaling-down-writes-on-0-percent: true

# Restric scale down to only happen when BOTH reads AND writes are in need
# of scaling down. Set this to "true" to minimize down scaling.
#always-decrease-rw-together: true

Note: The configuration of tables support regular expressions so you could write [table: log_* ] if you want to target multiple tables with one config section.
