Overall Satisfaction with Amazon DynamoDB

DynamoDB is used across the Engineering department. The biggest use case was introduced by me a couple of years back where our largest production workload was migrated to DynamoDB from Cassandra.

  • Auto-scaling is the best feature which no other product offers.
  • Predictable performance with good latency metrics.
  • Its 100% server-less and fully managed which makes engineer's lives easier.
  • Global Table is not the best solution yet and needs to be improved.
  • Does not do well in the case of globally replicable counters.
  • Cost of GT might be excessive and not feasible for most companies with big production-write workloads.
  • Cost savings over Cassandra.
  • Less of a maintenance hassle and less downtime for the services running on it.
Predictable performance and it meets our SLA expectations.
Amazon DynamoDB is well suited for high-traffic workloads which vary across the day. The autoscaling feature helps to reduce the running cost for off-peak hours.

It is not suitable for counters especially when they need to be replicable. The item size is also important. If it's trying to read too much, it might not give the best performance.
