Better read replica performance, at a lower cost

Springtail provides scalable read replicas for Postgres databases on Amazon RDS. You can scale up compute nodes for heavy workloads, and scale down during low usage to reduce costs.

Works with AWS Postgres

Seamlessly replace your Amazon RDS for PostgreSQL or Aurora PostgreSQL read replicas with Springtail.

On-demand scaling

Instantly scale compute up or down for read replicas. Pay only for the capacity you need, when you need it.

Fast replication

Deploy additional read replicas in seconds. No tedious setup or lengthy syncing delays.

OVERVIEW

Elastic read scaling for your existing Postgres infrastructure on AWS

Architecture

Springtail is a cloud-native distributed database that separates storage from compute, providing seamless horizontal scaling for read-heavy workloads.

Our service works alongside your existing Amazon RDS infrastructure, offloading and scaling reads while your Amazon RDS for PostgreSQL or Aurora PostgreSQL remains the trusted, primary store of data.

Springtail scales read performance alongside your existing Amazon RDS for PostgreSQL database.
Features

Maximize throughput, minimize overhead

Documentation

Say goodbye to over-provisioned read replicas.
With Springtail, you only pay for the performance you need—when you need it.

Unlike RDS replicas that are always-on at full capacity, Springtail offers on-demand scaling, reducing overhead and saving you money.

Scaled compute

Scales replica compute nodes up or down to match workload requirements.

Autoscaled storage

Seamlessly increases storage capacity as your data volume expands.

Load balancing

Distributes queries across replicas with consistent and optimized performance.

Read/write splitting

Coming

Offloads read queries to Springtail, sends write traffic to your primary Amazon RDS.

compatibility

Works with your existing AWS Postgres instance

Built on native Postgres replication. Zero migration.

Springtail connects to your existing Postgres instance.
It streams changes from your primary database in real time, letting you scale out read workloads without changing your existing infrastructure.

Documentation

Real-time data sync

Streams data changes from your primary using Postgres logical replication.

Schema change tracking

Captures DDL changes with triggers to keep schemas in sync across nodes.

Postgres frontend

Utilizes Foreign Data Wrappers to expose the replicated data as Postgres tables.

Automatic query fallback

Routes unsupported queries, like inserts/updates/schema changes, back to the primary.
