+## `CUBEJS_HASHER_ALGORITHM`
+
+The hashing algorithm used for cache keys, query hashes, and pre-aggregation versioning. Changing this value will invalidate all existing cached data and pre-aggregations. MD5 is used by default for historical compatibility; SHA-256, SHA-512, and [xxHash][xxhash-ref] are also available. Performance may vary based on the specific workload and environment, so it's recommended to benchmark different algorithms to determine the best fit for your use case.
