Hi Wes,
I will certainly give that a shot and provide feedback - my typical setup with
arrow has so far used ExternalProject and I tend to prefer this for development
vs the install path since it makes it easier track problems, step into the
code, run arrow examples and tests when I need a
hi Radu,
If you use the approach in
https://github.com/apache/arrow/blob/master/cpp/examples/minimal_build
It should be sufficient to use
find_package(ArrowFlight REQUIRED)
and then use the imported arrow_flight_static target (or
arrow_flight_shared, depending on your needs) when linking. If
I can produce something isolated shortly - but really the questions is how can
one build a hello world type flight server that does something like
{
FlightServerBase server;
server.Serve();
//Yes I know this would fail at runtime but I just need to get there first
}
with a fully self
Hi,
Could you share a minimal CMake and C++ file set to
reproduce your case?
Thanks,

Hi,
The following code will work:
auto list = std::static_pointer_cast(data->chunk(0));
auto currentSeries = list->value_slice(rowIndex);

Hello,
I am trying to build a server that uses arrow flight and getting into a bit of
a rabbit hole with dependency inclusion.
I have arrow included as an external project and so far everything has worked
really smoothly (I have executables building with arrow, parquet arrow and I
also have
I think I found a way:
```
// data is arrow:ChunkedArray
auto list = std::static_pointer_cast(data->chunk(0));
auto values = list->values();
auto startOffset = list->value_offset(rowIndex);
auto length = list->value_offset(idx + 1) - startOffset;
Some of you may have noticed a sudden flurry of activity from me after a
bit of a break from the project, so I thought it might be useful to explain
what I am up to.
As of 1.0.0, DataFusion isn't really useful against any real-world data
sets for a number of reasons, but most of all due to the
I have a ChunkedArray of type `arrow::list` and I want to take a value
for a particular row in this column and return it as Array.

`values` method and also take `value_offset` to get offset. This way I
will get pointers to the whole
Support for reading nested Parquet data is incomplete, see ARROW-1644.
I hope this will be completed by the end of this year

I use the Arrow-1.0.0 to parse parquet and meet that error.
Is there any way or plan to deal with it?
