# Which Database as a Service (DBaaS) platforms handle ultra-low latency for high-throughput workloads?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Latency requirements that look fine in a demo often fall apart under real production throughput. Here's what reviewers in the <a class="a a--md" elv="true" href="https://www.g2.com/categories/database-as-a-service-dbaas">Database as a Service (DBaaS) category</a> say holds up at scale:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/amazon-web-services-aws-amazon-dynamodb/reviews"><strong>Amazon DynamoDB</strong></a>: Reviewers cite consistent single-digit-millisecond performance even under heavy read and write volume, the most frequently cited option for this specific need.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/couchbase/reviews"><strong>Couchbase</strong></a>: Reviewers in high-throughput applications cite in-memory caching layered with persistent storage as the reason latency stays low under load.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/google-cloud-bigtable/reviews"><strong>Google Cloud BigTable</strong></a>: Reviewers cite strong throughput for very large datasets, though the learning curve is steeper than DynamoDB's according to several reviews.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/arango/reviews"><strong>Arango</strong></a>: A smaller review base, but reviewers cite multi-model flexibility without the latency tradeoff some multi-model databases carry.</li>

&lt;p&gt;Oh Amazon DynamoDB is built explicitly for this, it&#39;s marketed and reviewed around single-digit millisecond latency at virtually unlimited scale, serverless, and it&#39;s the classic pick for high-throughput applications like gaming leaderboards, ad-tech bidding, or session storage. Amazon RDS is the other AWS-native option, but it&#39;s a traditional relational database as a service, so it&#39;s excellent for consistency and complex queries, not really optimized for the same ultra-low-latency, massive-throughput profile as DynamoDB. Couchbase is worth a look too, well-rated and known for combining low-latency key-value access with more flexible querying than DynamoDB offers. To be real, &quot;ultra-low latency&quot; for DynamoDB assumes simple key-based access patterns, if your workload needs complex joins or transactions across many tables, that changes the calculus toward a different engine. What&#39;s the access pattern, mostly simple key lookups, or complex relational queries at high volume?&lt;/p&gt;
