A PERFECT BALANCE

Combine the best of SQL and LMDB

PowerDNS Lightning Stream makes synchronizing zone updates in the PowerDNS Authoritative Server seamless and efficient. It synchronizes changes between a local LMDB (Lightning Memory-Mapped Database) and an S3-compatible bucket in near real-time. This enables efficient one- or two-way replication, accelerating and scaling data transfer between authoritative PowerDNS instances.

Lightning Stream is especially beneficial for distributed and large-scale deployments. It significantly simplifies DNS replication and ensures a globally consistent view of the data within seconds. It supports the synchronization of zone data and DNSSEC keys across multiple PowerDNS Authoritative Servers, even in environments with multiple concurrent write operations.

Key Benefits:

  • Replication between data centers with S3 bucket synchronization
  • Ensures provisioning continues even in the event of a data center failure
  • Supports both one-way and two-way synchronization
UPGRADE
TAKING SYNCHRONIZATION TO THE NEXT LEVEL

Lightning Stream for Enterprise

Lightning Stream for Enterprise extends the scope of Lightning Stream by introducing incremental synchronization. Incremental synchronization is a true game-changer for large-scale PowerDNS deployments. Instead of transferring entire databases, only the changes are synchronized between authoritative servers and S3 storage, reducing data transfer volumes significantly. For organizations with frequent updates to large databases, this means:

Much Faster Replication

Updates propagate between authoritative instances in just a few seconds.

Lower Bandwidth Consumption

Improved Efficiency

Regular Full-Syncs

TOGETHER
LIGHTNING STREAM AND CLOUD CONTROL

Unite the Benefits

LMDB with Lightning Stream serves as the default backend for cloud-native deployments of the Authoritative Server using PowerDNS Cloud Control. PowerDNS Cloud Control provides a centralized management layer for DNS servers, while Lightning Stream ensures lightning-fast synchronization between them. Together, they deliver a highly available, scalable, and fault-tolerant DNS infrastructure — ideal for large or distributed networks.

Centralized Management

Faster, More Reliable DNS Synchronization

High Availability & Fault Tolerance

Scalability for Large Networks

Lightning Stream Benefits at a Glance

Speed & Scalability
Based on LMDB backend, the fastest Authoritative Server backend with scalability to very large numbers of zones and records.

Low Operational Complexity
No need for SQL database knowledge. S3 buckets are provided "as a service" by internal or external PaaS.

Enables Up-to-date Architectures
Multi-primary architectures across multiple data centers and secondary-style architectures.

Cloud-native DNS
Default backend for PowerDNS cloud-native deployments with PowerDNS Cloud Control. Ideal for large or distributed networks.
