BetterDB – open-source Redis/Valkey migration across clouds and self-hosted

15 points by kaliades 61 days ago | 6 comments

I built this after a year at Redis as an engineering manager for their developer tools, watching the ecosystem fragment after the license change.

Redis 7.4 broke data file compatibility with Valkey. RIOT, the only widely-used open migration tool, was archived last October with no open replacement. And the clouds - AWS, GCP, Redis Cloud - have no incentive to make leaving easy. If you want to move between providers, switch protocols, or get off managed infrastructure entirely, you're on your own.

BetterDB ships a three-phase workflow to fix that:

Analysis - scans your keyspace and flags blocking incompatibilities before anything moves. Green/amber/red verdict.

Execution - RedisShake for same-protocol speed, or command-based for cross-version and cross-protocol migrations where binary transfer fails.

Validation - key count comparison, sample spot-check, and performance baseline comparison against pre-migration snapshots.

Any direction. Any provider. Standalone or cluster.

The most useful Redis pattern I've found for real-time data: write with explicit TTLs and let stale data expire naturally instead of invalidating. If your writer dies, the data expires on its own within the TTL window. No stale data served indefinitely. Simple but surprisingly hard to break

The simplest approach is the best in 90%+ of the cases!
