What Heimdall Database Proxy is

Heimdall Database Proxy is a data access layer between applications and databases that routes, caches and secures SQL queries. It sends reads to replicas and writes to primary databases, using replication-lag detection to support consistency. Frequent queries can be cached with automatic expiry and invalidation rules to reduce load and latency. Connection pooling can reduce front-side to back-side connections by up to a 1000:1 ratio. Live SQL visibility identifies bottlenecks and provides auto-tuning recommendations. The proxy can run as a transparent sidecar on-premise or in the cloud, with Linux and self-hosted deployment. Supported databases include MySQL, PostgreSQL, Amazon RDS, Oracle, SQL Server, MariaDB, DB2, Greenplum and Redshift. Enterprise Plus adds data masking, GDPR auditing and honey-tokens. A free Greenplum Community Edition and a free 30-day trial are listed; paid tiers have quote-based pricing.
