`extract_vectors_from_batches` validated a null `_ROW_ID`, row-id contiguity, a null vector row, the dimension and a null element — but not finiteness, so a `NaN` or `±inf` embedding was indexed silently. The everyday cause is a cosine normalisation dividing a zero vector by its zero norm. Java rejects these per element in `LuminaVectorGlobalIndexWriter#checkFinite`, covered by `testNanInVectorRejected` and `testInfinityInVectorRejected`. The other Rust vector backend rejects them too, in `paimon_vindex_core`'s `validate_finite_values` on both the write and the query side — so switching `index.type` between the two backends turned a loud build failure into a silent one. The message carries the row id and the position inside the vector, as Java's does: a rejected build is only actionable if the offending row can be found. -- This is an automated message from the Apache Git Service.
