Hi @levakin, what would be your opinion on this? Is it something we can easily add?
hi @marcboeker , it should be doable. The only tricky thing is Note that after running duckdb_arrow_array_scan, duckdb_destroy_arrow_stream must be called on the out stream.
this part.
Maybe it can implemented using a pattern with something similar to cancel
function being returned.
Thanks @levakin for the evaluation. Would it make sense to add a method that returns an ArrayScanner which has to be closed afterwards?
I wanted to take a look at this the other day, but didn't know where to start.
Extend the Apache Arrow interface support to expose
duckdb_arrow_scan
andduckdb_arrow_array_scan
functions. (seems like onlyduckdb_query_arrow_schema
is supported for now)duckdb_arrow_scan duckdb_arrow_array_scan
This would be useful for fast data loading directly from Arrow types.
