text: **DynamoDB Accelerator (DAX) In-memory acceleration**
  
  In most cases, the DynamoDB response times can be measured in single-digit milliseconds. If your 
  
  use case requires a response in microseconds, is read-heavy, or has bursty workloads, DAX provides 
  
  fast response times for accessing eventually consistent data, increased throughput, and potential 
  
  operational cost savings.
