Starburst Gateway

Starburst Gateway is a load balancing solution that routes traffic to Starburst Enterprise platform (SEP) clusters based on rules you configure. It allows you to direct traffic across complex deployments with multiple clusters.

Starburst Gateway serves as a single entry point for your SEP clusters. It directs queries to the appropriate SEP cluster based on routing rules, resource availability, and other criteria you define.

Use cases

Query routing

Smart routing directs queries to specific routing groups based on query criteria you define. A routing group contains one or more clusters. The gateway routes the query to the cluster with the lowest query concurrency. If you do not configure currency metrics, the gateway routes the query to a random cluster.

Blue/green deployments

Blue/green deployments allow zero-downtime cluster upgrades. Starburst Gateway shifts traffic from an existing cluster (blue) to a new cluster (green). Use blue/green deployments to:

• Deploy a new SEP version alongside your current version

• Test your new deployment with limited traffic

• Migrate workloads without service disruption

• Roll back your changes if you detect issues

High availability and disaster recovery

Starburst Gateway reduces downtime by automatically routing traffic away from failing clusters. Configure Starburst Gateway to:

• Detect when a cluster fails

• Route queries to healthy clusters

• Ensure continuous service during maintenance
