...operating systems, and hardware architectures, can also cause changes in ordering. This page documents the cases where non-determinism is an expected behavior . If you would like to make your queries determinisic, see the “Working Around Non-Determinism” se...ction . Set Semantics One of the most common sources of non-determinism is the set semantics used by SQL. E.g., if you run the following query repeatedly, you may get two different results: SELE...ple 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 are some cases where deterministi... - https://man.mtool.work/duckdb/1.3/operations_manual/non-deterministic_behavior.h...
