Changelog

We released Eden v1.0.0, marking a major production-ready milestone. This release introduces migration performance throttling to prevent overwhelming source databases, canary migration tests that validate data integrity on a subset before full migration, and real-time latency monitoring for performance debugging. Redis now properly handles binary keys across all data types, and MongoDB wire protocol validation has been hardened to reject malformed messages.

Eden's MongoDB proxy now includes built-in protection against CVE-2025-14847 (Mongobleed), a critical vulnerability affecting MongoDB versions 3.6 and later that allows remote memory reads via crafted compressed messages. Our wire-protocol validation blocks attacks by checking for mismatched length fields, excessive uncompressed sizes (>256MB), and invalid zlib headers before malicious payloads can reach your MongoDB server—all with under 100µs of added latency.

We introduced a new MCP server for migrations, enabling AI assistants like Claude to orchestrate database migrations through natural language. The MCP transport layer now uses streamable HTTP for lower latency and better connection handling. We also added comprehensive Redis command coverage tests and migration success rate guardrails that automatically pause migrations if error rates exceed thresholds.

Redis connections are now pinned through WATCH/MULTI/EXEC transaction blocks, ensuring that optimistic locking and atomic operations work correctly during migrations. The request analyzer now supports custom template registration for identifying application-specific query patterns.

Eden databases can now be cloned from snapshots, enabling instant creation of staging environments or point-in-time recovery. We added PSYNC support to the Redis proxy for efficient partial resynchronization, and implemented comprehensive observability for migrations including key counts, throughput metrics, and error categorization.

Eden's LLM endpoints now support streaming with tool calling, allowing AI models to invoke database operations mid-response for real-time data retrieval. We migrated from r2d2_redis to deadpool for connection pooling, reducing connection overhead by 40% and eliminating rare connection leak issues under high concurrency.

Eden now runs natively on ARM64 (Apple Silicon and AWS Graviton), with Docker builds completing 3x faster using native compilation. The interlay proxy layer now supports TLS for encrypted connections between proxy components, and we standardized structured JSON logging across all services for better observability.

We implemented SwitchProxy, a traffic routing layer that enables zero-downtime database migrations by gradually shifting traffic from source to destination. The proxy handles connection draining, automatic failback on errors, and provides real-time traffic split visibility. Organization-level super admin creation now works correctly across multi-tenant deployments.

We optimized the Redis interlay with zero-copy parsing, reducing memory allocations by 60%. Criterion benchmarks were added to catch performance regressions in CI. Helm charts are now available for deploying Eden on Kubernetes, with configurable resource limits, horizontal pod autoscaling, and Prometheus metrics endpoints.

We added MongoDB wire protocol support, enabling Eden to proxy MongoDB connections alongside Redis. Redis-to-Redis migrations now achieve throughput of ~10MB/s or approximately 150,000 keys per second on typical workloads, with automatic batching and pipelining to maximize efficiency.
