  1. 1. Auto scale DynamoDB with Dynamic DynamoDB Sebastian Dahlgren! @sebdah
  2. 2. Project overview Throughput metrics via CloudWatch Supports auto scaling of
 tables & global secondary indexes

  3. 3. Background Auto scaling is important! - Saves money
 - Saves your skin No auto scaling in DynamoDB
  4. 4. Basic config example
  5. 5. Configuration • [global]   o AWS credentials o Check interval o Circuit breaker • [logging]   o Logging settings o Supports external logging config • [table:  my_table]   o Rules for scaling a certain table o Maintenance windows • [gsi:  my_gsi  table:  my_table]   o Rules for scaling Global Secondary Indexes
  6. 6. Handling many tables or dynamic table names • Table list refreshed for every iteration o Addition of new tables o Removal of old tables
 • Use regular expressions in your configuration [table:  ^daily_data.*$]
  7. 7. Scaling down • DynamoDB limits down scaling to 4 times per UTC day • Optimize downscaling by using
 o reads-­‐lower-­‐threshold
 o writes-­‐lower-­‐threshold
 o always-­‐decrease-­‐rw-­‐together
 o maintenance-­‐windows
  8. 8. SNS notifications • Get an email when your provisioning is updated
 • Currently supports: o scale-up o scale-down
  9. 9. Circuit breaker • Dynamic DynamoDB can poll an URL to check system health
 • All scaling is paused if the URL does not return HTTP 200  OK
