- Non-Deterministic Behavior 9414
- Several operators in DuckDB exhibit non-deterministic behavior. Most notably, SQL uses set semantics, which allows results to be returned in a different order. DuckDB exploits this to improve performance, particularly when performing multi-
...s query, both [A, B] and [B, A] are valid results. Floating-Point Aggregate Operations with Multi-Threading Floating-point inaccuracies may produce different results when run in multi-threaded configurations: For example, stddev and corr may produce non-dete.... However, when executed on multiple threads, the query may return small numbers ( 0 <= z < 10e-16 ) due to floating-point inaccuracies. Working Around Non-Determinism For the majority of use cases, non-determinism is not causing any issues. However, there a... - https://man.mtool.work/duckdb/2.0/operations_manual/non-deterministic_behavior.h...
