Sophon main now refreshes an eligible materialized view incrementally, appending what an append-only source added since the last refresh, a day after the change that made every refresh a full rebuild. So the materialized view page and the REFRESH reference no longer say recent versions rebuild in full: they say recent versions run views as SQL jobs, need no stable row ids and take no refresh options, and that a full or incremental refresh depends on the version and the view's query. COPY is described with the same "recent versions" wording.

<Warning>
|
|
Recent deployment versions refuse `COPY` over the SQL endpoint with "COPY is not
|
|
supported". On those, export a result by reading it through a Flight SQL client
|
|
or an SDK and writing the files from your application.
|
|
</Warning>
|
|
|
|
```sql
|
|
COPY (SELECT id, title FROM documents) TO 's3://bucket/export/' STORED AS PARQUET
|
|
```
|
|
|
|
Writes a query result to object storage. This is the export path when the
|
|
consumer is another engine rather than an application -- results land as files
|
|
rather than streaming to a client.
