-**`QUANTILE <float>`** — (scalar only) calibration quantile for the INT8 conversion; defaults to Qdrant's built-in default (0.99) when omitted.

-
-**`ALWAYS RAM`** — keep the **original**(unquantized) vectors in RAM for rescoring, sacrificing memory savings but preserving accuracy during re-ranking. Supported by all three types.

-**`ALWAYS RAM`** — keep the **quantized** vectors in RAM at all times, regardless of the collection's `on_disk` setting. Improves search throughput at the cost of higher RAM usage for the compressed index. The original full-precision vectors are stored and managed independently of this flag. Supported by all three quantization types.

-**`QUANTIZE`** always appears **after** all other clauses (`HYBRID`, `USING MODEL`, etc.).

- For `PRODUCT`, the compression ratio is fixed at **4×** in this version.

- When used with `HYBRID` collections, quantization applies only to the **dense** vector.
## DUMP COLLECTION — export collection to a .qql script file

Export every point in a collection to a `.qql` script file. The generated file is valid QQL — it can be re-imported with `qql execute` to restore or migrate the collection. Points are written in batches of 50 as `INSERT BULK` statements.

Export every point in a collection to a `.qql` script file. The generated file is valid QQL that re-creates the collection and re-inserts all payload data. Points are written in batches of 50 as `INSERT BULK` statements.

> **Scope of a dump:** The generated script preserves collection topology (dense vs hybrid) and all point payloads. It does **not** preserve quantization config, pinned model / vector dimensions, or payload indexes — those must be re-applied manually after import if needed.
