KeyDB's "engine" (often abbreviated as "eng" in technical contexts) is built on several key architectural pillars:

This design trades off perfect scalability for 80% of workloads (single-key or same-shard operations) while remaining correct for the rest.

: If you want to reduce your cloud bill by using fewer, larger instances instead of dozens of small ones.

For read-heavy workloads (90% GET, 10% SET), KeyDB can exceed on the same hardware.
